Active intermediates in the photolysis processes of compounds Ph_3M (M=N, P, As, Sb, Bi) have been studied with the combination of spin trapping technique, column chromatography and ESR spectrascopy. From the hyperfine structures of the ESR spectra of the spin adducts formed between active intermediates and spin trapping reagents such as phenyl tert-butyl nitrone (PBN), nitrosobutane(t-BuNO) or nitrosodurene (ND), the free radical Ph. has been identified in the photlysis of Ph_3M (M= P, As, Sb, Bi) and Ph_2M·+Ph·. As the average bond energies of Ph—M decrease in the order Pb—P>Ph—As>Pb—Sb>Ph—BiPh_2M· (M=As, Sb, Bi) decompose much easy than that of Ph_2P·, so they could not be observed in out experiment.
