ESR and spin trapping-ESR method was used to study the photocatalytic oxidation of carbazole at surface of CdS particle. Carbazole nitroxyl radical was first obtained and its haif period is about 10 ~ 20min , g value is 2.0060. The resuts also show that the production of carbazole nitroxyl radical may be described by degenerated branch chain reaction scheme.
