Abstract
SEVERAL workers have reported on the electron spin resonance spectra of allyl radicals in various glassy matrices1–3. The observed spectra are poorly resolved because of large anisotropic interactions3. Recently I have observed well-resolved electron spin resonance spectra of ‘allyl-type’ radicals in irradiated polycrystalline tetra-alkyl ammonium halides at room temperature. The spectra were recorded on a Varian electron spin resonance spectrometer with 100 kc/s field modulation. The experimental details are similar to those published previously4.
