✦ Synopsis

The dependence of the fluoresrrnce spectra of some aromatic hydrocarbons and phthalocybines in solid solutions at 4.2 K on the frequency of laser excitation has been studied. It has been found that "multiplets" exist in the fluorescence spectra in the c-a-se when laser excitation occurs in the vibronic transition region. 'the structure of these "multiplets" does not depend on the solvent but changes considerably with a change of laser frequency. It has been shown that by dysing the above-mentioned "multiplets" one an obtain frequencies of vrbrations of the investigated molecules in excited electronic states.
