Abstract
Single crystals of thymidine irradiated with 4.0 MeV electrons exhibit the well-known eight-line e.s.r. spectrum due to the 5-thymyl radical. A careful analysis of these lines revealed an extra hyperfine splitting, which by a combination of INDO-MO calculations and experiments, was attributed to an interaction between the unpaired electron and the N3-H group.
摘要
用4.0兆电子伏电子辐照胸苷的单晶，由于5-胸腺嘧啶自由基而呈现出众所周知的八线电子自旋共振谱。对这些谱线的仔细分析揭示了一种额外的超精细分裂，通过INDO-MO计算和实验相结合，这种分裂被归因于未配对电子与N3-H基团之间的相互作用。
