摘要/Abstract

摘要： 利用流动余辉技术研究了亚稳态氦与CHBr₃、CH₂Br₂的传能反应。由激发态碎片的发射光谱测定了CH(A,B,C)等碎片的相对布居、形成速率常数和CH(A²Δ,v'=0)的转动温度,并对传能反应机理进行了初步的讨论。

关键词: 传能反应, 流动余辉, 亚稳态氦, CH₂Br₂, CHBr₃

Abstract: In this paper the energy transfer reaction of He(2³S) with CHDr₃and CH₂Br₂has been investigated by the flowing afterglow technique. Based on the emission spectra of excited fragments we estimated the relative populations and formation rate constants of CH(A, B, C). The rotational distribution of CH(A²△, v'=0) and reaction mechanism were discussed.

Key words: Energy transfer reaction, Flowing afterglow, Metastable state He, CH₂Br₂, CHBr₃
