Q: Is ACS Omega an SCI journal?
To check if your manuscript is indexed in the ISI Web of Science, you can log on to the following url http://mjl.clarivate.com/. Once you log in you can simply search by the full journal name or the ISSN number. The search result will show if your target journal is indexed in SCI, SCI-E, or ESCI. Please note that all SCI, SCI-E, or ESCI indexed journals are under the ISI web of science database.
I searched using the title ACS Omega and the search results showed that the journal is indexed in SCI-E (Science Citation Index Expanded). However, I would recommend that you check it yourself once before making a decision.
