The excited electronic states of biacetyl CH3COCOCH3 have engaged the attention of many researchers over the past forty years. Interest has centered primarily on the lowest excited singlet state and the nearby triplet state lying slightly lower in energy. Early work involving biacetyl concentrated on the lifetime, yield, and quenching rates associated with the phosphorescence from triplet state molecules both in solution and in the vapor phase. Subsequent interest in biacetyl was related to its use as a gas phase emission standard and as a triplet energy acceptor in the study of triplet molecule participation in the photochemistry of other molecules. The literature on these aspects of the study of biacetyl has been extensively reviewed. More recent work involving biacetyl has used the behavior of this molecule to test theories of radiationless transitions.
