Abstract

The cholesteryl benzoate compound has been irradiated with 60Co-γ rays at room temperature. The irradiated samples have been examined for paramagnetic resonance, and in several cases the observed spectra could be identified with specific radicals. In each case the results have been considered in relation to the present knowledge of the radiation chemistry of the compound. The single crystals have been investigated between 123 and 300 K. The spectrum parameters are found to be temperature independent. Radiation damage centers are attributed to ĊHCH2 and ĊHCH2CH2 radicals. The g values and the hyperfine coupling constants of the unpaired electron with the protons were determined.
