Abstract:In the field of chemical science, the development of new drugs, the formation of crystals and molecular clusters, and the optimization of drug safety and efficacy are all closely related to weak molecular interactions. In this paper, the salicylic drugs 4-aminosalicylic acid (4-ASA) and 5-aminosalicylic acid (5-ASA) are used as the research objects. First, the terahertz (THz) absorption spectra of the two isomers were measured in the range of .4-2.0 THz by terahertz time-domain spectroscopy (THz-TDS). Then the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
