摘要：
The UV irradiated triarylsulfonium salts decompose under formation of phenyl radicals. Using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) spin trap the formation and the decay of .DMPO-Ph adduct was followed during the irradiation and after irradiation stop at various DMPO and Ph3S+BF4- concentrations. The experimental data observed were well fitted by the simulation and are in good agreement with the kinetic model suggested. The technique developed can be effectively used in various kinetic investigations.
