dc.descriptionWe summarize a few proposals for mixing F center states through the mediation of an appropriate symmetry-breaking vibrational mode. Electron-mode coupling energies odd-order in the mode coordinates are characteristic of the pseudo-Jahn-Teller mixing of nearly-degenerate opposite-parity electronic states mediated by an odd-parity vibrational mode. Coupling energies even order in the vibrational coordinates lead to a pseudo-Renner mixing of even parity nearly-degenerate states or to dynamic-Renner mixing of degenerate states of whatever symmetry. Both Renner mixing energies add up to widen the crossover splitting of the adiabatic energies thereby enhancing the nonradiative deexcitation rate.
