Difference between Frequencies of Optical Absorption and Circular Dichroism Maxima–One Mode Approximation–

Abstract

Theoretical analysis is made for the electron-vibration interaction effects on frequencies ν max A and ν max C D of optical absorption and circular dichroism maxima. Simple formulae of the frequency difference ν max C D - ν max A are obtained in terms of electron-vibration interaction parameters for the case that one specific vibrational mode is important. Application of the theory is made for visual pigments.
