Revised assignment of the electron spin resonance spectrum obtained during photolysis of N-(diphenylmethylene)methylthiomethylamine N-oxide. The bis(methylthiomethyl) nitroxide radical

Abstract

Photolysis of N-(diphenylmethylene)methylthiomethylamine N-oxide, Ph₂CN(→O)CH₂SCH₃, yields bis(methylthiomethyl) nitroxide, (CH₃SCH₂)₂NO, rather than, as previously reported, the diphenylmethylene(methylene)-amine N-oxyl radical, [Ph₂CN(O)-CH₂]˙. The e.s.r. spectrum of (CH₃SCH₂)₂NO shows an alternating line width effect at ambient and lower temperatures.
