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.
摘要
通过电子自旋共振（ESR）和电子核双共振研究确定的某些γ射线辐照的甾体激素和胆固醇中形成的自由基的分子结构已得到综述。还分析了分子间相互作用和氢键对所形成自由基结构的影响，以及羟基取代对α-超精细分裂张量的影响。
