title: EPR/ENDOR investigations of gamma-irradiated steroid hormone single crystals.
abstract: The molecular structure of free radicals formed in certain gamma-irradiated steroid hormones and cholesterol determined by electron spin resonance (ESR) and electron nuclear double resonance studies has been reviewed. The influence of intermolecular interactions and hydrogen bonds on the structure of the radicals formed, as well as the effect of substitution of hydroxyl group on the alpha-hyperfine splitting tensor have also been analyzed.
