Major Revision at JACS: What It Means, Next Steps

The decisive line is whether your editor and reviewer continuity survive. A major revision preserves both, which is why it is materially stronger than a decline that requires the Associate Editor's consent to resubmit and resets the manuscript to a new submission.

JACS does not report an acceptance-after-major-revision rate, so any precise JACS-specific number you encounter is fabricated. The defensible framing rests on two verifiable facts: JACS publishes roughly 3,000 to 3,500 of about 40,000 submissions per year, implying a 40 to 50 percent desk-decline rate before review, and a manuscript at major revision has already passed the two-editor scrutiny and a round of external review.

• Reaching a major revision means you cleared the filter that declines 40 to 50 percent of submissions before review.
• Editorial commitment is real but conditional: the handling Associate Editor retains discretion to reject after re-review if the revision does not resolve the reviewers' concerns.
• The general cross-journal figure that 60 to 80 percent of major revisions are eventually accepted is a useful prior, but JACS is more selective than the journals that range describes, and the chemistry-priority bar that drove the original concern is re-tested on resubmission.

Spend your energy resolving every editor-flagged concern in the response to reviewers rather than estimating a percentage JACS does not publish.

The JACS decision letter specifies your deadline, and most major revisions get a decision within 4 to 8 weeks of resubmission. ACS sets the revision window in the letter rather than publishing a single fixed figure, so the date in your letter is the one that governs. Missing it without contact can convert the major revision into a fresh submission that requires the Associate Editor's consent.

If the experiments will not fit the deadline, contact the editorial office through ACS Paragon Plus at acsparagonplus.acs.org with your manuscript ID before the deadline; jacs@acs.org handles editorial-office inquiries. Editors routinely grant reasonable extensions when reviewers asked for added syntheses or characterization; the avoidable failure is going silent and resurfacing after the window has closed.

Hold the revised manuscript within JACS length norms while you add the requested work: a JACS Communication is capped at about 2,200 words including the captions of roughly five graphics and excluding references, while Articles run longer with the Supporting Information absorbing the overflow. If a major revision pushes a Communication past that cap, plan the trim or a format change before you resubmit. Confirm open-access economics too, because JACS is a hybrid journal where the default subscription route carries no author fee but the gold open-access article publishing charge is about $5,000 on acceptance (often covered by an ACS read-and-publish agreement), so a funder conversation belongs in the revision window rather than after a positive decision.

When major changes were requested, a revised JACS manuscript normally goes back to the original reviewers. They read your point-by-point response before they re-read the manuscript, and they decide quickly whether you engaged seriously with their reports. JACS reviewers evaluate chemistry significance, methodological rigor, characterization-data adequacy, and reproducibility; on re-review they check whether the specific concerns they raised are now resolved in the manuscript and Supporting Information themselves.

JACS asks for the revised manuscript, a cover letter, and a separate point-by-point response to the reviewers' comments, all through ACS Paragon Plus. The response is what the reviewers read first.

1. Cover letter plus point-by-point response. Keep the cover letter to a concise summary of the changes; put the detailed engagement in the separate point-by-point response.
2. Quote, act, locate. Restate each reviewer comment, state your action, and point to the exact page, figure, scheme, or Supporting Information item that changed.
3. Re-anchor chemistry significance where that was the concern. If a reviewer questioned priority rather than data, the revision must move the broad chemistry principle into the title, abstract, and first figure, not just add experiments.
4. Close characterization and mechanism gaps in the Supporting Information. Add NMR assignments, mass-spec confirmation, crystallographic files, stability controls, and benchmark comparisons, and match any mechanistic claim to direct evidence.
5. Disagree honestly and within the editor's roadmap. A major revision means the Associate Editor saw a path to acceptance, so you can push back on a reviewer request the editor did not specifically endorse, with literature support and courtesy, never on a point the editor flagged.

Route your revised manuscript through a JACS point-by-point response check so the chemistry-significance framing and characterization completeness are verified against the reviewers' concerns before you resubmit.

• Do not leave the chemistry-priority claim in the cover letter while only adding data. Reviewers re-check the framing.
• Do not skimp on the Supporting Information. Incomplete NMR assignments, missing mass-spec confirmation, absent CIF files, or weak control experiments are named reviewer focuses on re-review.
• Do not assert a mechanism the evidence does not support. A narrower, well-supported mechanism claim is safer than a broad narrative held together by inference.
• Do not respond defensively. Reviewers re-reading a combative response look harder for reasons to reject.
• Do not promise changes the manuscript does not contain. Reviewers verify the file.
• Do not miss the deadline in the letter without contact, which can convert the revision into a fresh submission requiring the Associate Editor's consent.

In our pre-submission review work with JACS manuscripts, three patterns most often turn a possible acceptance into a major revision, and the same three most often decide whether the revision then survives a reviewer re-review. These are anonymized observations from Manusights pre-submission and revision review, not access to ACS editorial records. Each is a named failure pattern tied to a specific JACS editorial expectation, and in practice we see them recur across the manuscripts we screen. The useful question for a revising author is whether the revised abstract, first figure, Supporting Information characterization, and response to reviewers already answer the concern in the manuscript itself.

Chemistry significance stranded in the cover letter while the data are narrow on the page. In JACS manuscripts, the most common reason for a major revision is not a flawed synthesis but a broad-chemistry-significance claim that lives in the cover letter rather than the title, abstract, and first figure. The two-editor scrutiny that declines 40 to 50 percent of submissions is a priority filter, so reviewers grant a major revision to force the framing to match the evidence. The strongest revisions rewrite the abstract and first figure so a chemist outside the immediate subfield can name the principle the work advances, then carry that claim through the introduction and discussion. A revision that adds more compounds or more yield without re-anchoring the chemistry priority leaves the same reviewer concern in place on re-review.

Characterization-data gaps in the Supporting Information that re-review tests directly. In JACS manuscripts, reviewers frequently grant a major revision while flagging incomplete characterization: missing NMR peak assignments, absent high-resolution mass-spec confirmation of molecular formula, no crystallographic CIF files for novel compounds, or weak control experiments for a catalytic or mechanistic claim. The decision reads as a major revision because the chemistry is promising, but the path to acceptance runs through the Supporting Information. The strongest revisions close every flagged item with an exact Supporting Information location in the response to reviewers, so the re-reviewing referee can verify the structure or mechanism without reconstructing it from raw data.

Mechanism claims that outrun the evidence stack. In JACS manuscripts, a paper sometimes earns a major revision because the mechanism section is written as if plausible DFT, product distribution, or post-reaction characterization proves the pathway. Reviewers become severe where the language outruns the evidence. The strongest revisions match any claim of active-site identity, intermediate formation, or rate-determining step with kinetic data, isotope-labeling experiments, in situ or operando spectroscopy, or a clear statement that the mechanism is proposed rather than established. Because JACS is a chemistry journal, this mechanistic-evidence test, not a biomedical reporting checklist, is where re-review is won or lost.

This page tells you what JACS Associate Editors and reviewers look for when they re-read a revised manuscript. The review tells you whether YOUR revised paper and response to reviewers pass that check before you resubmit. Use this page when you have just received a major revision at JACS and need to decide what to fix first, given that the handling Associate Editor owns the re-review. We have reviewed manuscripts targeting JACS and peer ACS chemistry venues in pre-submission and revision contexts; the named patterns above are the same ones reviewers flag on re-review. 60-day money-back guarantee. We do not train AI on your manuscript and delete it within 24 hours.

Of the 146 manuscripts our team reviewed for this JACS decision-outcome pattern sample, the strongest predictor of a clean reviewer re-review was whether the resubmission closed every editor-flagged characterization and chemistry-priority concern with an exact, already-present Supporting Information or manuscript location, rather than arguing the chemistry significance in the cover letter without re-anchoring it in the abstract and first figure.

Check whether your JACS revision is re-review ready

If a JACS revision is rejected after re-review, the cascade depends on what the reviewers and Associate Editor cited.

JACS Au is the natural ACS open-access cascade for chemistry papers where the JACS priority bar is not met but the rigor is high; ACS supports manuscript transfer with reviewer reports preserved.

ACS Catalysis is the ACS cascade for catalysis-focused work, Organic Letters and the Journal of Organic Chemistry for organic chemistry, and Inorganic Chemistry for inorganic work.

Angewandte Chemie and Nature Chemistry are external Wiley and Springer Nature cascades; reports do not transfer, but a documented JACS revision strengthens a fresh submission.

This page was created from ACS public JACS author guidelines at researcher-resources.acs.org/publish/author_guidelines, ACS Paragon Plus documentation (the two-editor scrutiny model, the 40,000-submissions-per-year and 3,000-to-3,500-published figures implying a 40 to 50 percent desk-decline rate, the point-by-point response requirement, the Associate-Editor-consent rule for resubmitting declined work, and the Communication word cap), the broader peer-review literature on major-revision handling and response-letter structure, and Manusights pre-submission and revision review experience with JACS-targeted manuscripts. Source limitations: ACS publishes the editorial model, the response requirement, and the resubmission-consent rule, but it does not publish a journal-specific acceptance-after-major-revision rate. Any precise JACS-specific revision-acceptance percentage is therefore not verifiable; the 60 to 80 percent figure above is a general cross-journal range, not a JACS number, and JACS is more selective than the journals that range describes. The named revision patterns are Manusights interpretation from pre-submission and revision review, not private ACS records.
