γ射线辐照嘧啶核苷水溶液的ESR研究

ESR STUDIES OF γ-RAY RANIATION ON AQUAEOUS SOLUTIONS OF PYRIMIDINE NUCLEOSIDES

用自旋捕集技术和ＥＳＲ方法，以ＭＮＰ为捕集剂，确定了嘧啶核苷（胸苷、尿苷、胞苷）的水溶液在γ射线辐照下所产生的自旋捕集自由基的类别，讨论了自由基形成的机制。

The aquoeus solutions of pyrimidine nucleosides radinted by γ-ray have been studied by spin trapping (MNP as trapping reegent) and ESR technique. The radicals of spin trapping yielded in uracil nucleoside, cytosine nucleoside and thrymine nucleoside solutions are certified, and the formation mechanizm of these radicals is disscused.
