✦ Synopsis

Sulfonamidyl free radicals, RSO$R', have previously been invoked as intermediates in a variety of reactions including thermal or photolytic addition and rearrangement reactions of Nhalosulfonamides and oxidative intramolecular cyclizations of sulfonamides*. However, in the absence of relevant spectral data, no unequivocal conclusions about the electronic structure of sulfonamidyls could be drawn and the radicals have been described in terms of both a o-or 'TIelectronic ground state 233 . In this communication we report the first electron spin resonance (ESR) spectral study of a series of simple aryl-and alkylsulfonamidyl radicals4. The transient

The asphaltene of the Athabasca bitumen exhibits a single, structureless e.s.r. signal at a g-value of 2.0032 with an intensity corresponding to approximately one free spin per ninety molecules. From the temperature dependence of the absorption it is concluded that absorption is due to stable polycy

## Abstract Fructans (GF~n~) are important constituents of some plants. A study of the radiolysis of fructans in solution was performed using the spin‐trapping method. Electron spin resonance, combined with high‐performance liquid chromatography and followed by spectral analysis with the simulation

## Abstract Solution and powder ESR spectra of the 4‐trifluoromethyl‐1,2,3,5‐dithiadiazolyl and 4‐pentafluorophenyl‐1,2,3,5‐dithiadiazolyl free radicals were analysed. Comparison of the ESR parameters with those obtained for the protonated equivalents shows that fluorination produces a drift of unp
