Article vs Communication and Format Norms (jacs-length-management)
When to trigger
- You must decide Article vs Communication
- The manuscript feels over- or under-length for the chosen format
- You are unsure what moves to the SI to fit format norms
- Figure/scheme count is high and needs disciplining
Choosing the format
| Question |
Communication |
Article |
| Is the core advance a single, urgent, high-impact result? |
Yes |
Often part of a larger story |
| Can full proof live in the SI with a concise main text? |
Yes |
No — needs full main-text treatment |
| Is broad scope / multi-system / deep mechanism central to the claim? |
No |
Yes |
| Timeliness vs completeness |
Timeliness dominates |
Completeness dominates |
Verify the current article types, length, figure, and word limits on the
JACS author page — these change and differ by format. Do not hard-code limits.
Right-sizing the main text
- Lead with the advance; the introduction should be tight (frame the gap, state the thesis).
- Results & Discussion carries only what proves the claim and its generality/mechanism; exhaustive variation goes to the SI.
- One headline scheme/figure per major point; merge panels rather than adding figures.
- Conclusion is short: what is established and what is now enabled.
What stays vs what moves to SI
| Keep in main text |
Move to SI |
| Central scheme/result and one scope figure |
Full substrate tables and optimization grids |
| Key mechanism figure + decisive evidence |
Complete kinetic/labeling datasets |
| Crystal-structure figure + CCDC # |
Full crystallographic tables, checkCIF |
| One or two essential spectra (if needed) |
All spectra copies, procedures |
Trimming tactics (without losing rigor)
- Convert prose describing a table into the table; delete the prose.
- Remove optimization narration; cite the SI optimization table for the chosen conditions.
- Cut redundant restatements between intro, results, and conclusion.
- Combine related schemes; move "also worked" examples to the SI scope table.
Checklist
Anti-patterns
- Choosing Communication for a story that needs Article-level support
- Padding an Article with optimization narration better suited to the SI
- Figure sprawl: many near-duplicate schemes instead of merged panels
- Hard-coding outdated word/figure limits instead of checking current norms
- Trimming so hard that a key claim loses its supporting evidence
Operating pass for Journal of the American Chemical Society
Treat this skill as an executable review pass, not a prose hint. First lock the chemical novelty, characterization chain, controls, and scope or mechanism evidence; then judge whether the current manuscript answers the venue's real reader: chemistry reviewers who expect a molecule/material/reaction claim to be supported by rigorous characterization and mechanistic insight.
-
Do the pass: Return a claim-evidence-risk ledger rather than a prose-only diagnosis; every recommendation must point to a manuscript location or missing artifact.
-
Return a ledger: give
claim / evidence / risk / manuscript location rows, so the next agent can edit rather than rediscover the issue.
-
Sibling guard: compare against ACS Central Science for broad conceptual reach, Angewandte for communication style, specialized ACS journals for narrower chemistry; if a sibling owns the contribution, recommend re-routing before polishing format.
-
Stop condition: do not give submission-ready advice until the pack's
resources/official-source-map.md has been checked for volatile rules and the manuscript has one concrete fix for the largest venue-specific risk.
