The pure radiative lifetime of ovalene was measured in a series of solvents. The effect of S1-S2energy gap reduction by the solvent on the pure radiative lifetime was studied and could be fitted to the theoretical calculations. Several questions are raised concerning the validity of the theory at small inter-electronic energy gaps. © 1986.
