Electron spin echo detection of laser photogenerated tetramethylbenzidine cation in liquid sodium dodecylsulfate micellar solutions at room temperature is reported. The phase memory time is 180 ns which can be identified with the transverse relaxation time. Deuteration effects on the phase memory time indicate that the cation interacts more strongly with surfactant molecules than with water molecules.
