ACS Omega Time to First Decision: What Authors Need to Know

By culbreath Editorial · 2026-10-08 · 4 min read

If you submit a manuscript to ACS Omega, the time from submission to the first editorial decision is typically around two to three weeks. This “acs omega time to first decision” metric reflects the journal’s emphasis on rapid peer review. The journal operates on a continuous publication model, meaning accepted papers are published online immediately after processing.

How the Review Process Works

ACS Omega uses a single-blind peer review system. When you submit a paper, the editorial team first performs an initial screening for scope, formatting, and basic quality standards. If the manuscript passes this check, it is assigned to an Associate Editor who handles the peer review.

The editor invites external reviewers, typically two to three experts in the field. Reviewers are asked to return their comments within a specific timeframe, usually two weeks. Because the journal focuses on technical soundness rather than perceived impact, reviewers have a clearer set of criteria to evaluate, which can speed up their assessment.

Once the reviews come back, the editor makes one of several decisions: accept, minor revision, major revision, or reject. The “first decision” refers to this initial verdict, not the final acceptance after revisions. For manuscripts sent out for review, the median time to this first decision is around 21 days ACS Omega. Manuscripts that are rejected without review (desk reject) receive a decision much faster, often within a few days.

What Affects the Timeline

Several factors can influence how quickly you get a decision.

  • Reviewer availability. Finding willing reviewers with the right expertise can take time. The journal maintains a large database of reviewers, but for highly specialized topics, the search may take longer.
  • Reviewer responsiveness. Most reviewers complete their reports on time, but some may request extensions. The editorial office sends reminders to keep the process moving.
  • Time of year. Submissions around major holidays or academic conference seasons may experience slight delays, as reviewers and editors are often less available.
  • Manuscript quality. A well-prepared manuscript with clear figures, proper formatting, and complete data is easier to evaluate. Submissions with missing information may require additional clarification before being sent for review.

What the First Decision Usually Looks Like

The most common first decision for ACS Omega is “revision required.” This is not a rejection. The journal encourages authors to address reviewer comments and resubmit a revised version. A “major revision” decision means the reviewers have identified substantial issues that need to be addressed. A “minor revision” decision indicates that the paper is largely acceptable but needs small corrections.

A “reject” decision at this stage usually means the reviewers found fundamental flaws in the methodology, the data does not support the conclusions, or the work falls outside the journal’s scope. Desk rejects typically occur because the manuscript does not meet the journal’s basic criteria or is clearly out of scope.

Example Timeline

Here is a rough timeline for a typical manuscript that undergoes full peer review:

Stage Estimated Time
Initial editorial screening 1-3 days
Reviewer invitation and assignment 3-7 days
Review period 10-14 days
Editorial decision 1-3 days
Total to first decision 15-27 days

This timeline assumes reviewers accept the invitation promptly. If one or two reviewers decline, the editor must invite replacements, which adds a few days.

How to Help the Process Run Smoothly

You can take several steps to avoid unnecessary delays.

  • Follow the author guidelines exactly. Format your manuscript according to the journal’s template. Include all required sections, such as a conflict of interest statement and data availability statement. Missing elements can cause your submission to be held up at the screening stage.
  • Write a clear cover letter. Explain why your work is suitable for ACS Omega. A brief statement about the scientific contribution and relevance helps the editor assign the right associate editor.
  • Suggest potential reviewers. The submission system allows you to recommend reviewers. Choose experts who are familiar with your specific topic and who have no conflicts of interest. This can speed up the reviewer invitation process.
  • Avoid common pitfalls. Make sure your figures are high resolution, your references are complete, and your abstract accurately summarizes the work. Reviewers are more likely to accept invitations for manuscripts that appear well-prepared.
