Electron spin resonance spectra and electronic structure of nitrophenoxatellurin anion-radicals

Abstract

The e.s r, spectra of mono- and di-nitrophenoxatellurin anion-radicals in different solvents are reported and interpreted in terms of solvent-induced line-width alternation. The perturbation effects of the nitro-group, oxygen, and tellurium are outlined by comparison with mono- and di-nitrodiphenyl ether anion-radicals. MO Calculations account well for the e.s.r. behaviour of these compounds.
