The triplet state of azulene has been produced in benzene by pulse radiolysis and a lifetime of 11 +/- 1 ..mu..s determined. This is longer than previously reported values. The identity of this species has been confirmed by witnessing its formation and quenching via essentially diffusion-controlled triplet energy-transfer processes involving respectively 1,3-cyclohexadiene as donor and perylene as acceptor. A triplet energy of 40.1 +/- 0.2 kcal mol/sup -1/ has been determined by establishment of an equilibrium for triplet energy transfer between anthracene and azulene. 26 references, 5 figures, 1 table.
