Abstract
A new nonperturbative method of considering quadratic vibronic interactions is proposed on the basis of linear relations between phonon operators in different electronic states. Equations for normalised Fourier amplitudes of resonance Raman scattering are obtained, which determine the Fourier transforms of absorption and luminescence spectra. On the basis of the method proposed, the temperature behavior of the zero-phonon line is displayed.Keywords
