Effect of linear coupling on vibronic energy levels and transition intensities in the Jahn-Teller T⊗τ problem

Abstract

We present a numerical solution for one-parameter linear Jahn-Teller coupling as it affects the full vibronic energy level spectrum of the T⊗τ problem. The Franck-Condon distribution of spectral intensities for the electronic transition from a totally symmetric originating state is characterized as a function of the linear coupling strength.
