Abstract
A molecular crystal is an attractive medium for the study of excited state intenmolecular interactions since the ground state positions of interacting molecules may be accurately determined. Besides excimer interactions in pure crystals it is possible to study (in doped crystals) exciplex interactions between host and guest molecules, and even excimer formation between two adjacent guest molecules. This approach has been utilized to observe excimer formation by several anthracene derivatives introduced as dopants in pyrene crystals. Photochemical reactions of some of these exciplexes and excimers are discussed. Excimer forming crystals are considered to be good candidates for excited state structure determination by means of pulsed x-ray diffraction.
