Quick answer: A JACS response to reviewers is three documents submitted through ACS Paragon Plus: the revised manuscript, a short cover letter to the associate editor, and a separate point-by-point response that reviewers read first. Quote each comment, answer directly, and end each response with the exact page and line, a note on whether you reference the original or revised file, so the reviewer can verify each change without re-reading the paper.
JACS associate editors hold revisions to the same bar as new submissions: chemical significance beyond your subfield, a mechanism backed by experiment, and complete characterization.

Use this guide before you submit a revision: this Journal of the American Chemical Society response to reviewers walkthrough is written by a senior chemistry researcher on the Manusights review team and last reviewed on June 6, 2026. The evidence basis is documented in the Sources section below: ACS author and reviewer guidance, the PLOS Ten Simple Rules, SciRev community reports, and our own pre-submission review of JACS-targeted resubmissions. We reviewed each claim against current ACS guidance when the page was produced.
What does a JACS response to reviewers require?
For Journal of the American Chemical Society, the revision package is the decisive document, not the manuscript edits alone. ACS journals ask for the revised paper, a cover letter, and a separate point-by-point response, all uploaded through ACS Paragon Plus. The associate editor and the original reviewers read the response first and use it to navigate your changes.
The single most-cited rebuttal mistake is changing the manuscript without telling the reviewer where. Every response to a comment must name the specific page and line of the revised manuscript where the change appears, and you should indicate whether the line numbers refer to the original or the revised version. "We have addressed this" with no location forces a reviewer to re-read the whole paper, and reviewers who cannot find your change assume you did not make it.
Element | What JACS expects | What gets flagged |
|---|---|---|
Structure | Point-by-point, each reviewer comment quoted in full | Free-form prose summarizing all comments together |
Location of changes | Exact page and line for every revision, original-vs-revised noted | "We have updated the manuscript" with no reference |
Significance | Reaffirm the broad-chemistry advance the editor screened on | Defending incremental scope without strengthening it |
Mechanism | New experimental or computational evidence, not restated claims | Asserting the proposed mechanism is "consistent with" the data |
Characterization | Missing spectra, purity, or yields supplied in the SI | Promising data "available on request" |
Tone | Direct, polite, substantive on science | Defensive on minor stylistic comments |

The JACS reviewer culture: significance, mechanism, and characterization
This is where JACS rebuttals differ from a generic response letter. JACS runs an associate-editor model: a working chemist in your subarea handles the paper and assigns reviewers, rather than a full-time professional editor. That associate editor screened your paper on three things, and the revision is judged on the same three.
First, significance and advance. ACS describes the editorial question as whether the advance changes how chemists beyond your immediate subfield think about a problem. A revision that only patches technical gaps without re-establishing the broad-chemistry case will satisfy a reviewer's narrow complaint and still leave the associate editor unconvinced the paper belongs in JACS rather than a specialist chemistry journal.
Second, mechanism. JACS reviewers routinely request that a proposed mechanism be supported by experiment rather than asserted. In practice this means a Hammett plot, a kinetic isotope effect, a control experiment that rules out an alternative pathway, or a computed transition state. In our analysis of JACS-targeted resubmissions, a response that argues the existing data are "consistent with" the proposed mechanism, without adding any of these, is the classic second-round-rejection pattern at JACS.
SciRev data for JACS shows the same thing from the author side: reviewers consistently ask for mechanistic evidence that the original submission did not supply.
Third, complete characterization. Because JACS spans synthetic, physical, analytical, and biological chemistry, reviewers expect full characterization data: NMR spectra, mass spec, elemental analysis or HRMS, purity, yields, and crystallographic data where relevant, almost always in the supporting information. A revision that says new compounds are "fully characterized" without putting the spectra in the SI invites a request for another round.
Key Insight
A JACS major revision normally returns to the same reviewers who raised the concerns. Your point-by-point response has to satisfy the specific people who already read the paper, not a generic editor, so vague answers that worked in a cover letter will not survive a second read.
A copyable JACS rebuttal letter template
Use this structure for the separate point-by-point response document. Replace the bracketed fields with your own content. Open with the cover-letter framing to the associate editor, then handle each reviewer in order, quoting their comment before each answer.
Dear Editor,
Thank you for the opportunity to revise our manuscript the manuscript title
(Manuscript ID [ID]) for the Journal of the American Chemical Society.
We are grateful to both reviewers for their careful reading. In response,
we have added [N control experiments / kinetic data / computed transition
states] that directly test the proposed mechanism, and we have supplied
complete characterization for all new compounds in the revised Supporting
Information.
Below we respond to each comment in turn. Reviewer comments are shown in
bold; our responses follow in plain text; manuscript line numbers refer to
the revised version unless noted.
----------------------------------------------------------------------
Reviewer 1
Comment 1.1: "The proposed mechanism is not supported by direct
experimental evidence."
Response: We agree and have addressed this directly. We added a kinetic
isotope effect experiment (k_H/k_D = [value]) that distinguishes the
proposed C-H activation step from the alternative pathway. These data
appear in revised Figure 3 (page 5, lines 142 to 158) and Supporting
Information Section S4 (pages S12 to S15).
Comment 1.2: "Characterization of compound 4 is incomplete."
Response: We have added full characterization for compound 4, including
1H and 13C NMR, HRMS, and elemental analysis, in revised Supporting
Information Section S2 (page S6). The yield and purity are now stated in
the main text (page 4, line 98).
----------------------------------------------------------------------
Reviewer 2
Comment 2.1: "It is unclear why this advance matters beyond the immediate
subfield."
Response: We have clarified the broad-chemistry significance in the revised
introduction (page 2, lines 31 to 47) and discussion (page 8, lines 240 to
255), where we now state explicitly how the method changes [the broader
chemical problem].
Comment 2.2: "An additional control is needed to rule out [alternative]."
Response: We respectfully note that this control is outside the scope of
the present study because the specific reason. As an alternative, we have
added [the relevant experiment] in revised Figure S7 (page S18), which
addresses the underlying concern.
We thank the reviewers again and believe the revised manuscript is
substantially strengthened.
Sincerely,
Corresponding author, on behalf of all authorsThe four tokens that make a JACS rebuttal credible are all present here: a clear opening to the editor, explicit Reviewer 1 and Reviewer 2 sections, action verbs that state what you did (added, clarified, revised), and a page-and-line reference for every change.
Tone calibration: defensible pushback vs counterproductive defensiveness
You will not agree with every comment, and that is fine. JACS associate editors expect substantive engagement, not capitulation. The line that matters is between defending the science with evidence and getting defensive about the critique itself.
Situation | Bad response | Better response |
|---|---|---|
Reviewer requests an out-of-scope experiment | "This experiment is unnecessary and beyond the scope of the paper." | "This control falls outside the present scope because [reason]; as an alternative we added [experiment] in Figure S7 (page S18), which addresses the same concern." |
Reviewer doubts the proposed mechanism | "The mechanism is well established and the reviewer is mistaken." | "We agree the original evidence was indirect. We added a kinetic isotope effect (Figure 3, page 5, lines 142 to 158) that distinguishes the two pathways." |
Reviewer flags missing characterization | "Full characterization was already provided in the original submission." | "We apologize for the omission. Complete NMR, HRMS, and EA for compound 4 now appear in SI Section S2 (page S6)." |
Reviewer asks for a clarification you find obvious | "This point is already clear in the text." | "Thank you, we have clarified this in the revised discussion (page 8, lines 240 to 255)." |
Reviewer raises a significance concern | "JACS has published similar work, so significance is not in question." | "We have sharpened the broad-chemistry framing in the introduction (page 2, lines 31 to 47) to make the advance explicit." |

The pattern across the Better column: accept the blame where you can, answer directly first, then point to evidence and a location. The pattern across the Bad column: argue with the reviewer rather than the science. Check your JACS response tone calibration before you resubmit if you are unsure which side of the line a given response sits on.
Typography: separate reviewer text from your response
A response document is unreadable if the reviewer cannot tell their words from yours. PLOS's Ten Simple Rules makes this explicit: use changes of typeface, color, and indenting to distinguish three different elements: the review itself, your response, and the changes you made to the manuscript. The template above uses bold for reviewer comments and plain text for responses; many JACS authors add a third color or an indent for quoted manuscript text.
Pick a scheme and apply it consistently across both reviewers. ACS Paragon Plus accepts the response as a standard document, so the typography you set is what the reviewer sees.

The page-and-line referencing rule, restated
Because it is the most common reason a reviewer asks for another round, it earns its own rule: every single response must end with a location. Page and line of the revised manuscript, figure or table number, and SI section. State once at the top of the document whether your line numbers refer to the original or the revised file, then never make the reviewer guess.
A response that quotes the comment, answers it, and then says "see revised Figure 3, page 5, lines 142 to 158" is a response a reviewer can verify in seconds. That speed is what gets your revision through the second round.
What pre-submission reviews reveal about JACS rebuttal failures
In our pre-submission review work with JACS submissions, three response-to-reviewers failure patterns generate the most consistent second-round trouble. Each is grounded in the same significance, mechanism, and characterization bar that JACS associate editors apply, and each is testable against your own response document before you resubmit.
The asserted-mechanism dodge. The most frequent failure across JACS-targeted resubmissions is responding to a "mechanism not supported by experiment" comment with more argument instead of more data. Authors restate that the existing kinetics or spectra are "consistent with" the proposed pathway and add no new experiment.
Across our JACS pre-submission reviews, this is the pattern most likely to convert a major revision into a rejection, because the revised manuscript returns to the original reviewer who already rejected the same reasoning. The fix is concrete: add at least one piece of distinguishing mechanistic evidence (a kinetic isotope effect, a Hammett plot, a crossover experiment, or a computed transition state) and cite it by figure and line number.
The characterization gap left in the cover letter. The second pattern is claiming complete characterization in the response while leaving the supporting information thin. Manuscripts coming through pre-submission review for JACS routinely answer a characterization comment with "compound X is fully characterized" but do not actually add the missing NMR, HRMS, elemental analysis, or purity data to the SI. JACS reviewers check the SI, not the assurance.
The response is only credible if the spectra are physically in the revised supporting information and the response names the SI section and page where they now live.
The significance answer that patches without re-arguing. The third pattern is the narrowest-to-spot and the most decision-relevant: authors answer every technical comment competently but never re-establish why the advance matters beyond their subfield. Of the JACS-targeted manuscripts we pre-screen, this is the failure that satisfies the reviewers and still loses the associate editor, who screened on broad-chemistry significance in the first place.
A strong JACS response treats the significance question as a first-class comment even when no reviewer phrased it that way: sharpen the introduction and discussion framing, and reference those exact lines in the response. Check whether your JACS rebuttal closes all three gaps before you upload to ACS Paragon Plus.
These are not theoretical concerns. A reviewer can hold your response next to your revised figures and SI and confirm in minutes whether each gap is actually closed. So can you, before they do.
Honest friction: a major revision can still be rejected
A major-revision decision at JACS is an invitation to try, not a guarantee. Roughly 40 to 50% of JACS submissions are desk-rejected before review, and a meaningful share of the papers that reach revision are still rejected on the second round when the response does not deliver the requested evidence. Most rejections-on-revision at JACS trace to the same root cause: the author treated a requested control experiment or characterization dataset as optional and argued around it instead of running it.
Think twice before resubmitting if any of these describe your response:
- The mechanism comment was answered with argument and zero new experimental or computational data.
- A characterization request was answered with text but no new spectra in the SI.
- More than one reviewer comment ends with "we believe this is sufficient" and no manuscript change.
- The response defends scope on an experiment that would genuinely strengthen the paper and that you could run.
- The broad-chemistry significance was never re-argued because no reviewer used that exact word.
If two or more of these apply, the realistic outcome is another round at best and a rejection at worst, and an appeal will not help because the reviewers are right that the evidence is missing. The faster path is to run the experiment now. JACS revision deadlines are typically set per decision letter, often around 4 to 8 weeks; if a control experiment needs more time, request an extension through ACS Paragon Plus rather than submitting a response that papers over the gap.
A realistic JACS revision timeline
Revision task | Typical duration | What happens |
|---|---|---|
Read and cluster reviewer comments | 1 to 2 days | Separate mechanism, characterization, and significance asks |
Run requested control or mechanistic experiments | 2 to 8 weeks | The rate-limiting work for most JACS major revisions |
Add characterization to the SI | 3 to 7 days | NMR, HRMS, EA, purity, yields for all new compounds |
Draft the point-by-point response | 1 to 2 weeks | Quote, answer directly, cite page and line |
Co-author review of response and manuscript | 1 week | Confirm every cited location is accurate |
Resubmit via ACS Paragon Plus | 1 day | Upload revised manuscript, cover letter, and response |
Second-round review by original reviewers | 3 to 6 weeks | Reviewers verify each change against your cited locations |

Frequently asked questions
Submit three things through ACS Paragon Plus: the revised manuscript, a short cover letter to the associate editor, and a separate point-by-point response. Quote each reviewer comment in full, give a direct answer first, then name the exact page and line you changed. The response is the document reviewers read first, so it has to stand on its own.
The same bar as initial submission: a chemical advance that matters beyond your subfield, a mechanism backed by experiment rather than asserted, and complete characterization. A revision that runs the requested control experiments and supplies the missing spectra clears faster than one that argues the data are already sufficient.
For major revisions, yes. The revised manuscript and your point-by-point response normally return to the same reviewers who raised the concerns, so your response has to satisfy the specific people who already read the paper, not a generic editor.
ACS revision deadlines are typically set per decision letter, often around 4 to 8 weeks for a major revision. If you need extra time for control experiments, request an extension through ACS Paragon Plus before the deadline rather than submitting an incomplete response.
Yes. A major-revision decision is an invitation to try, not an acceptance. If the revision does not supply the mechanistic evidence or characterization the reviewers asked for, the associate editor can reject on the second round. Treat every requested experiment as load-bearing.
