โœฆ Synopsis

From 8r1 analysis of the internal rate pamnetffs of the pyrene excimer in soWian in propyLneglym1, isopro-pano1 and other solvents it is concluded that fi) fhe radiitire transition rate (kg&, norm&z& to a medium of n=1, is independent of the solvent, (iii the temperatu&ndependent radiafionIess kansition rate kb is due to intersystem crossing, and (iiii the temperat~~epe~ent radiationbss transition: rate & is due to interna conversion, induced by thermally-activated molecular motion which is subject to vismus reskaint by the sotint.

We analyze electronic radialionless transitions in molecular aggregates in the limit where the coupling between the monomeric units is strong. We show that in this limit the rate at a given electronic energy gap decreases drastically with the increase in zhe size of the system. The dccrcase becomes
