Electron Spin Resonance Studies of Gamma-Irradiated Single Crystals of Sucrose

Abstract

The electron spin resonance of gamma‐irradiated single crystals of sucrose has been measured at 9400 Mc/sec for various orientations in the magnetic field. The variations of the resonance with angle were greatest for rotation of the crystal about its b axis, which was kept perpendicular to the magnetic field. The anisotropic hyperfine structure was observed to vanish when the magnetic field is applied perpendicular to the (b, c) plane. It was ascertained that the radical formed is the type X—CH–Y, which had been proposed by Williams et al. from the data obtained from the polycrystalline samples.
