利用氢原子里德堡态飞行时间谱技术研究HN3分子在紫外光(190?248 nm)光照射下的H+N3通道的光解动力学结果.通过测量H+N3通道的产物平动能分布以及产物的角分布,得到了在不同波长光解下N3产物分子的振动态分布. 实验结果表明, 在大于225 nm时,HN3分子主要是通过一个排斥态解离的.而在低于225 nm时,有一个慢的通道从220 nm 开始出现.这一新的解离通道是一个闭环产生环状N3产物的通道.当光解能量增加时,这一新通道相对的变得越来越重要. 相似文献

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. 相似文献
