Reaction Dynamics for Fundamental Types of Chemical Transformations

这项研究，在实验物理化学计划中，旨在了解量子态水平上的气相反应动力学。对于在地面电势表面进行的反应，将获得通过红外化学发光或激光诱导荧光测量的新的振动产物分布。将开发改进的实验技术，以增强在松弛发生之前观察反应产物旋转分布的能力。对于在电子激发表面进行的反应，将从可见光和紫外光荧光中识别产物状态。激光激发技术将被用来准备初始反应物状态。要研究的反应涉及稀有气体原子和稀有气体原子与卤化分子的范德华络合物。

This research, in the Experimental Physical Chemistry Program, is aimed at understanding gas phase reaction dynamics at the quantum state level. Nascent vibrational product distributions, measured by infrared chemiluminescence or laser-induced fluorescence will be obtained for reactions proceeding on ground potential surfaces. Improved experimental techniques will be developed to enhance the ability to observe rotational distributions of reaction products before relaxation occurs. Product states will be identified from visible and ultraviolet fluorescence for reactions proceeding on electronically excited surfaces. Laser excitation techniques will be used to prepare the initial reactant states. The reactions to be studied involve rare gas atoms and van der Waals complexes of rare gas atoms with halogenated molecules.
