Abstract
The 1(2)B(2)-->3(2)B(2) transition in the absorption spectrum of the benzyl free radical has been recorded in the vapor phase together with a new band at shorter wavelengths, probably the first Rydberg band of the radical in the vapor phase. The photolysis flash was of short duration and it was possible to follow the kinetics of the radicals' decay, which occurred predominantly by bimolecular recombination.
摘要
在气相中记录了苄基自由基吸收光谱中从1(2)B(2)到3(2)B(2)的跃迁，同时还记录到一个位于较短波长处的新谱带，它可能是该自由基在气相中的首个里德堡谱带。光解闪光持续时间很短，因而能够跟踪自由基的衰变动力学，其衰变主要通过双分子复合发生。
