Popis:	The zero-field electron magnetic resonance spectra of electron-irradiated powders of glycylglycine, carbamylglycine, glycocyamine, and acetylglycine all present six broad bands which are readily interpreted as resulting from the interaction of the electron magnetization with the proton left at the damaged site in the molecule. High field studies have shown that in such radical species there is also a weaker coupling with a neighboring nitrogen nucleus. We use simulated spectra to study the effect of this additional coupling and to derive corrected values of the components of the coupling tensor of the proton, which we believe to be more accurate than those obtained at high field.
