利用高灵敏度的氢原子里德堡飞渡时间谱方法研究了 F+H_2→HF+H 反应碰撞能在5.02kJ/mol 下的交叉分子束反应态态散射动力学.所有在时间飞渡谱中被观测到的谱峰可以归属为 HF 产物的振转态结构.还观测到了明显的 HF(v’=3)前向散射,以及少许的 HF(v’=2)前向散射.
The scattering kinetics of cross-molecular beam reaction at a F + H 2 → HF + H reaction collision energy at 5.02 kJ / mol was studied by using Rydberg-Fitt time-frequency spectroscopy with a high sensitivity of hydrogen. The observed peaks can be attributed to the oscillatory structure of the HF product, and significant forward scattering of HF (v ’= 3) and a little of forward scattering of HF (v’ = 2) were also observed.
