We analyze electronic radiationless 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 the size of the system. The decrease becomes more striking for larger electronic energy gaps. Extrapolation to the very strong limit prevailing in polyconjugated systems of major biological importance is suggested.
