摘要

For nonadiabatic electron-transfer reactions,it is common to make a Condon approixmation assumption that the mixing marix element is independent of nuclear geometry.We test the validity of the Condon approximation using Mulliken-Hush analysis applied to the biphenyl alcohol moleculae at varous geometries.Calculations of the energy splitting and electronic coupling matrix elecmne tas functions of geometry using semiempirical and ab initio mthds are presented.Breakdown of the Condon approximation is observed,quantified,and analyzed.
