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.

研究了作为反应中间体的加氢自由基的物理性质。通过将氢原子加成到中性分子如氨、烷基氨和杂芳族分子如吡嗪等上而产生的超价自由基的形成，进行，并发现，通过调查的氢键分子簇与各种溶剂分子的电子状态，这些自由基的寿命延长溶剂化。
