If UT doesn't have a subscription or other paid access to a restricted journal, you can look for open versions of a paper. These include preprints, post-publication copies, or peer-reviewed accepted manuscripts -- that have been deposited in open, legal repositories. You can also contact the author and ask for a copy.
If you'd rather not hunt for open copies yourself, there are browser add-ons that can automatically perform this function for you when you land on a paywalled article:
Chemistry doesn't have a strong preprint tradition like Physics, but there's a growing number of platforms for the free deposit and open dissemination of manuscripts prior to acceptance and publication in journals.
