Electron Spin resonance measurements were performed for the chromanoxyl radicals obtained from tx-, ~-, ~,-, /i-tocopherol, tocol and their model compounds by oxidizing the phenol precursors with PbO2 in toluene. The proton hyperfine coupling constants were determined, and the 'experimental' spin de
In dimethylformamide the ESR spectra of the radical anions of dibenzoCf,h]quinoxaline and dibenzo[a,c]phenazine both exhibit line broadening due to slow molecular tumbling over a wide temperature range. Similar effects are also observed in the spectra of the radical anions of quinoxaline and phenazi
Free radicals generated from a-and/3-ionyl bromides gave well resolved ESR spectra, but retinyl bromide and chloride gave only broad signals. Delocalised radicals were also spectrosopically observed on hydrogen abstraction from a-ionane, a-ionyltrimethylsilylether and buten-3-ynyl-2,6,6-trimethyl-2-
