Abstract
In photolysis of 4,4'-diazidodiphenyl sulfide quintet ESR peaks were o bserved and the plots of these signal intensities vs. temperature obey ed the Curie law, although no quintet signals were observed in the pho tolysis of 4,4'-diazidodiphenyl ether. The ESR spectrum upon the irrad iation of 3,4'-diazidodiphenyl sulfide showed quintet resonances of 3, 4'-dinitrenodiphenyl sulfide. Both Curie analysis and PM3-CI calculati ons indicated that the quintet state is a ground-state.
