光解碎片平动谱中二级过程的运动学及化学动力学
摘要:
本文发展了一套分析处理分子束光解反应实验中二级分解产物飞行谱的方法, 它改进了Kroger和Riley的最初讨论。本文表明许多重要的信息都可以从高度平均的实验数据中得出。这包括二级分解产物的平均平动能分布、空间各向异性参数、平行竞争通道间的反应比。模拟的结果可以表现二级分解反应的一些主要特征。

Modeling Simulation of Secondary Processes in Photofragment-Translational Spectroscopy
Abstract:
We developed a method for analyzing time-of-flight spectra of Secondary products from sequential dissociation reactions fol-lowing photon absorption by the parent molecule. This work complements the original discussion by Kroger and Riley, and shows that substantial information can be extracted even from highly aveyaged data. This information includes the average translational energy release and anisotropy of the secondary pro-duct recoil, as well as the relative yields of the secondary frag-ments for competing pathways. Model results are examined in order to illustrate the basic features of secondary dissociation.
