โœฆ Synopsis

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 more stnkmg for larger electronic energy gaps Extrapolation to the very strong limit prevailing in polyconjugatcd systems of major biological importance is suggested.
