【摘要】 本文使用LIF方法在气-束装置上研究了Ca+NF₃——CaF+F₂N 和Ca+CHF₃——CaF+CHF₂二个反应的初始产物能态分布。通过测得的CaF分子的LIF激发光谱和计算机模拟计算,发现二个反应的CaF振动分布属于类Boltzmann型,并取得其内能分配的信息。通过光谱模拟和信息论计算,还获知NF₂和CHF₂自由基的内能态是激发的。根据分析,本文认为这二个反应是具有后期释能特征的直接碰撞反应。更多还原

【Abstract】 The state population distributions of the nascent products for Ca+NF₃→CaF+ NF₂ and Ca+CHF₃→-CaF+CHF₂ reactions were studied by means of LIF in a beam- gas arrangement. From the LIF spectra of CaF and the computer simulations, the CaF vibrational distributions for both reactions were found to be similar to the Boltzmann distribution and the internal energy disposal of CaF was determined quantitatively.The results of the spectral simulation and the information theory computation indicate that NF₂ and CHF₂ radicals were vibrationally and rotationally excited. These two reactions are thought to be direct collision reactions with the "late" exoergicity on potential surface.更多还原
