Abstract
Laser flash photolysis of phenazine (PZ) solution reveals the existence of a stable species with a long lifetime at 380Â nm in addition to the usual triplet PZ at 440Â nm. The former is suggested to be due to formation of triplet PZ excimer. The triplet excimer also undergoes photoinduced electron transfer with some aromatic amines. The formation of PZ dimer anion radical and amine cation radicals are confirmed by external magnetic field effect studies. Measurement of B1/2, which estimates hyperfine present in the system, also supports this assignment.
