Abstract

A vibrational analysis of the fluorescence and fluorescence-excitation spectra obtained by the Shpol’skiĭ method at 4.2 K has been carried out. The parameters of the intramolecular interactions of two <i>δ</i>-dimethylaminoketones have been calculated. To determine the overall intensities of the vibronic bands in spectra with fine structure on an intense continuous background, the spectra have been modelled by representing the band of each of the vibronic transitions by a zero-phonon line and a phonon wing with definite parameters (the half-widths and the Debye–Waller factor). It is shown that the breakdown of mirror symmetry in the conjugate fluorescence and fluorescence-excitation spectra of these two compounds can be explained by the interference of the Franck–Condon and the Herzberg–Teller interactions.
