Dynamical Jahn-Teller Systems: Internal Energy Resonance Structures of Isolated Jahn-Teller Molecules (E-b and T-t System)

Abstract

Abstract The internal energetic transfer processes of an E - b and T - t Jahn-Teller system are con­ sidered. The first system allows an exact description, whereas in the case of the second one ap­ proximations must be introduced in the region of intermediate electron-phonon coupling strengths. The occupation probabilities of the states of the uncoupled systems change with time by virtue of the electron-phonon interaction. The energies are directly related to these occupation probabilities. The resonant nature of the T - t system is reflected in the internal dynamics of the latter.
