A mechanism for delayed fluorescence is considered in which the interaction of two molecules in their triplet states is followed by nonradiative transitions to a dissociative singlet state. The energies of the bimolecular states formed from the 3La states of some aromatic hydrocarbons are calculated. The rates of nonradiative transitions from the singlet and triplet bimolecular states are shown to be much faster than the rate of the quenching of triplets in solutions. It is also shown that nonradiative transitions from the quintet bimolecular state may compete favorably with triplet quenching.
