Dynamics of Non-Adiabatic Processes

在化学系物理化学计划的这个项目中，芝加哥伊利诺伊大学的R.J.戈登教授将在非绝热反应的一般领域进行分子动力学的各种研究。将进行两种类型的实验：光解和双分子反应。在第一类研究中，包括臭氧中避免交叉的研究，氯乙烯光解的多途径研究，以及氯化氢的光解离研究。第二类包括B态激发的一氧化碳与Ar的碰撞，氢原子与氯化氢的反应动力学，氯原子与溴化氢的反应动力学。反应化学中的非绝热电子跃迁是一个重要的课题，本项目研究了许多实验系统。除了具有根本意义外，光解离研究还涉及环境金属问题。

In this project in the physical chemistry program of the Chemistry Division, Prof. R. J. Gordon of the University of Illinois at Chicago will pursue a variety of investigations in molecular dynamics, in the general area of non-adiabatic reactions. Two types of experiments will be performed: photodissociation and bi-molecular reactions. Among the first type are studies of avoided crossings in ozone, multiple pathways in the photodissociation of chloroethylenes, and the photodissociation of hydrogen chloride. Included in the second type are investigations of the collision of B-state excited carbon monoxide with argon, and the reaction dynamics of atomic deuterium with hydrogen chloride and of atomic chlorine with hydrogen bromide. The subject of non-adiabatic electronic transitions in reactive chemistry is an important one and a number of test systems are investigated in this project. Besides being of fundamental interest, the photodissociation studies also have bearing on environmetal issues.
