“…ACs with single-atom modifications (sam_ACs) include “atom-replacement ACs” (ar_ACs) that contain a single-atom replacement (N to C (N-C), O-C, N-O, or S-O) at a given position and “atom-walk ACs” (aw_ACs), in which two analogs are only distinguished by the position of a single heteroatom (non-carbon atom). …”

“…Additionally, the spectrum of the intermolecular interactions was identified and studied from classical, relatively strong N-H···O and O-H···O hydrogen bonds through weaker N-H···S hydrogen bonds to weak interactions (for instance, C-H···O, C-H···S and N···O). The results of these studies point toward the importance of including both the geometrical features and the details of the electron density distribution in the analysis of such weak interactions.…”
