Abstract

We present a model of excimer formation based only on the most generic features of dimerized lattices such as those found in the excimer-forming molecular crystal α-perylene. The modulation of resonance integrals by lattice vibrations is found to cause significant effects consistent with the known characteristics of excimers and the related Y states. A specific calculation of the thermally-activated transition rate from the Y state to the excimer state is in good agreement with experimental observations.
