Abstract
The autoradiolytic and the gamma-induced demethylation of solid thymine were measured qualitatively and quantitatively for the first time with specially purified thymine-(methyl-14C). Analogous experiments with thymine-(methyl-3H) and radio-gaschromatographic analysis provided proof for the formation of molecular hydrogen and methane. Ethane was not detected. The results are discussed in connection with e.s.r.-spectroscopic studies.
摘要
首次使用经过特殊纯化的胸腺嘧啶-（甲基-14C）对固体胸腺嘧啶的自辐射分解和γ诱导的脱甲基作用进行了定性和定量测定。用胸腺嘧啶-（甲基-3H）进行的类似实验以及放射性气相色谱分析为分子氢和甲烷的形成提供了证据。未检测到乙烷。结合电子自旋共振光谱研究对结果进行了讨论。
