ESR Study of Intramolecular Magnetic Interactions in Bis(nitrenophenyl) Sulfides

Article abstract of DOI:10.1246/cl.1994.1679

In photolysis of 4,4'-diazidodiphenyl sulfide quintet ESR peaks were observed and the plots of these signal intensities vs. temperature obeyed the Curie law, although no quintet signals were observed in the photolysis of 4,4'-diazidodiphenyl ether.The ESR spectrum upon the irradiation of 3,4'-diazidodiphenyl sulfide showed quintet resonances of 3,4'-dinitrodiphenyl sulfide.Both Curie analysis and PM3-CI calculations indicated that the quintet state is a ground-state.
