Molecular chirality plays a fundamental role in life. The amino acids and sugar have two stereochemical isomers. That is, there are left-handed and right-handed forms. They show the different features to circularly polarized light. The efficiency of absorption is different and rotates the polarization axis. These optical activities are called circular dichroism and optical rotation, respectively. Theoretical bases of circular dichroism are reviewed. They are derived by classicai electromagnetism and also by quantum mechanics, and indicate there needs a nonzero value of the inner product of electric dipole transition moment and magnetic dipole transition moment to gain the optical activity. The formulae from the classical and modern theories are compared and correlated.
At the last part of this review article, we report our preliminary results of vibrational circular dichroism measurement of a ring compound to investigate the ability for prediction and analysis of the observed spectrum by using purely theoretical calculation. We also report the potential ability of vibrational circular dichroism for studying the molecular structure in solution, particularly the complicated system where there is a conformational multiplicity and hydrogen bonding.
