氢(或氘)原子与溴分子之间的化学反应是典型的轻-重-重(LHH)动力学体系之一,其理论和实验研究都很有趣.Jaffe和Clyne用激波管共振吸收(DFRA)技术测量了H+Br_2在295K下的反应速率常数.研究过渡态性质需要反应速率常数对温度的依赖关系,为此,Wada等利用脉冲辐射共振吸收(PRRA)技术测量了214—295K温度范围内H+Br_2
The chemical reaction between the hydrogen (or deuterium) atom and the bromine molecule is one of the typical light-heavy-heavy (LHH) kinetic systems, and both theoretical and experimental studies are interesting. Jaffe and Clyne use shock tube resonance absorption DFRA) technique was used to measure the reaction rate constant of H + Br_2 at 295 K. To study the transition state properties, the temperature dependence of the reaction rate constant was required. For this reason, Wada et al. Measured the temperature of 214-295K using pulsed radiation resonance absorption (PRRA) Range of H + Br_2
