Abstract:
A crossed molecular beams, state-to-state scattering study was carried out on the F+H2→HF+H reaction at the collision energy of 5.02 kJ/mol, using the highly sensitive H atom Rydberg tagging time-of-flight method. All the peaks in the TOF spectra can be clearly assigned to the ro-vibrational structures of the HF product. The forward scattering of the HF product at v′=3 has been observed. The small forward scattering of the HF product at v′=2 has also been detected. Detailed theoretical analysis is required in order to fully understand the dynamical origin of these forward scattering products at this high collision energy.

摘要:
利用高灵敏度的氢原子里德堡飞渡时间谱方法研究了F+H2→HF+H反应碰撞能在5.02 kJ/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.
