Effect of Lattice Dynamics on Intramolecular Electron-Transfer Rates in Mixed-Valence Complexes

Abstract

It is shown that the rates of intramolecular electron transfer for mixed-valence complexes in the solid state are not determined only by the electronic and vibronic coupling in the molecular complex. Lattice dynamics associated with the motion of ligands, solvate and counterions, which sometimes are manifested as phase transitions, frequently influence the electron-transfer rate.
