Abstract:

Possible calculation traps, which frequently appeared in absolute configuration determinations, are discussed here. These include (1) how to avoid falling into the traps during using various software in calculation procedure, (2) how to use simplified models to representative original chiral molecules, and (3) to find limitation of some software and the premise of their application. Some suggestions are provided for the resear-chers who are not very familiar with the calculation procedures to avoid falling into the traps during the calculations of optical rotation(OR), electronic circular dichroism(ECD), vibrational circular dichroism(VCD), and 13C nuclear magnetic resonance(NMR) spectra. Some examples are given for readers to understand the details in the absolute configuration determination procedures.
