A role of hydrogen atom-added peptide radical as a reaction intermediate in electron-capture dissociation reaction

对被认为是反应中间体的氢原子自由基的物理性质进行了研究。通过在中性分子如氨、烷基氨和杂芳烃分子如吡嗪等中加氢生成超价自由基，通过研究与不同溶剂分子氢键分子簇的电子态，发现这些自由基的寿命在溶剂化后延长。

The hydrogen atom-added radicals which have been considered to be an reaction intermediate were investigated about the physical properties. The formation of the hypervalent radicals, which are generated by addition of a hydrogen atom to neutral molecules such as ammonia, alkyl ammonia, and heteroaromatic molecules, for example pyrazine etc., were performed, and it was found that, by investigating the electronic state of the hydrogen-bonded molecular cluster with various solvent molecules, the lifetimes of these radical lengthen upon the solvation.
