  • Conformational Polymorphism Analysis of Aspirin Crystal with a Crystal Calculation Method  [in Japanese]

    OBATA Shigeaki , GOTO Hitoshi

    … In order to explore the possible polymorphs of aspirin crystal recently discovered in the subtle crystal packing form, conformational analysis of aspirin monomer and conformational polymorphism analysis of aspirin crystal were carried out using CONFLEX/KESSHOU (CONFLEX/K) which have implemented all functions of our crystal calculation program KESSHOU into our molecular mechanics program CONFLEX having an efficient conformational space search method. …
