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

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-
Electron spin resonance (ESR) and electron nuclear double resonance (ENDOR) measurements were performed for the cation radicals obtained from the model compounds of c~-, #-, 3'and 6-tocopherol (vitamin E) by oxidizing the tocopherol precursors in an AICI3-CHaCI a solution. The proton hyperfine coupl
## Abstract Fructans (GF~n~) are important constituents of some plants. A study of the radiolysis of fructans in solution was performed using the spinβtrapping method. Electron spin resonance, combined with highβperformance liquid chromatography and followed by spectral analysis with the simulation
