Electron Spin Resonance of an Irradiated Single Crystal of N-Carbamyl Glycine

Abstract
The electron spin resonance spectra of γ‐irradiated single crystals of N‐carbamyl glycine have been measured at 9 and 23 kMc/sec for various orientations of crystals in the external magnetic field. From the analysis of the hyperfine‐interaction constants the free radical produced by γ irradiation is found to be [Complex chemical formula] The spin density at the carbon atom is 75% and the free radical is similar to that produced from acetylglycine and glycylglycine.
