Abstract
Abstract: Quantum-mechanical microscopic reversibility of vibronic transitions and Boltzmann thermal distribution of the initial (starting) states substantiate method to obtain pure-electronic transition frequency from diffuse absorption or emission spectra. It is shown, that the information is obtainable immediately from linear and circular dichroism spectra or ratio of polarization spectra when the spectra present non-identical ensembles of chromophores. The examples to obtain pure-electronic gap from experimental spectra of linear or circular dichroism are given. The approach allows selecting molecular chromophor ensembles by polarization and evaluating their combining states zero-gap.
