Abstract
General statements concerning the self-trapping of excitons in crystals are given. Special attention is paid to the problems of the most importance as applied to molecular crystals. In this respect, two possible types of self trapping barriers are considered, viz., electronic and lattice barriers. They control the rate of the exciton capture from a free into a partial relaxed self-trapped state and the subsequent transition from the latter into a completely relaxed excimer state. From this viewpoint existing experimental fluorescence data related to the rate of exciton self-trapping in α-perylene and pyrene are discussed.
