✦ Synopsis

A three-site model for bridged tied-valence dimersis discussed. Adiabatic potential energy surfaces which depend upon the vibrational sum and difference coordinates are obtained. Intensities of the vibronic transitions which contribute to the intervalence transfer band shape are calculated using population-weighted Franck-Condon factors. We show that the Iineshape is dominated by the sum coordinate and not the difference coordinate when the electron exchange coupling is strong.
