Abstract
Two approaches to the analysis of fluorescence spectra of pyrene have been considered. In the first case, the profile of excimeric bands is investigated. The influence of defects in pyrene crystals over their fluorescence spectra is described by the potential of the monomer-dimer interaction, which is determined by the treatment of derivative fluorescence spectra. Second technique is based on the study of temperature dependencies in pyrene excimeric spectra and leads to the determination of some energetic parameters for excimeric potentials.
