VIBRATIONAL ABSORPTION AND CIRCULAR DICHROISM STUDIES ON CARBOHYDRATES

Abstract

Vibrational circular dichroism (VCD) of simple carbohydrates have been measured in the $1600-800 cm^{-1}$ region. Various configurational correlations are found. In order to understand these correlations with the nature of vibrations that are associated with VCD features, time dependent absorption spectra of parent and deuterated glucose molecules and a few other carbohydrates were investigated. Also the geometrics and force constants for $\alpha$ and $\beta$ glucose anomers were investigated using CNDO molecular orbital theory.
