Continuous 337nmlaser excitation of N,N,N′,N′-tetramethylbenzidine (TMB) in 0.1 mol dm–3 sodiumdodecylsulphatemicelles produces monophotonic ionization of the molecule. A study of the photoionization process has resulted in the following new results: (1) the radical-cation quantum yield decreases with adsorbed light because of its spectral overlap with TMB and its simultaneous photodestruction
