State-to-State Studies of Molecular Dynamics

在化学系物理化学计划的这个项目中，加州大学欧文分校化学系的Kenneth C.Janda教授将对稀有气体卤素范德瓦尔斯化合物的光谱和动力学进行一系列研究。其中包括HeBr2和NeBr2系统。不仅要研究它们的结构，特别是要确定它们弱相互作用的势能。将使用尽可能高分辨率的光谱学来获得关于Br2以及HeBr2、NeBr2和ArBr2电子态的实验数据。我们将研究ArBr2的分子内振动能量再分配动力学。这项工作将扩展到Br2嵌入大的He和Ne团簇的络合物中。这一研究对于理解含卤素大分子团簇的相互作用具有重要意义。它为发展弱成键分子络合物的结构和动力学模型提供了基准数据。

In this project in the Physical Chemistry program of the Chemistry Division, Professor Kenneth C. Janda of the Department of Chemistry of the University of California at Irvine will pursue a series of investigations on the spectroscopy and dynamics of rare gas- halogen van der Waals compounds. Among these are the HeBr2 and NeBr2 systems. Not only are their structures to be investigated, but especially the potential energies of their weak interactions are to be determined. Spectroscopy at the highest possible resolution will be employed to obtain experimental data on the electronic states of Br2, and on HeBr2 , NeBr2 and ArBr2. Intramolecular vibrational energy redistribution dynamics in ArBr2 will be investigated. This work will be extended to complexes in which Br2 is imbedded in large He and Ne clusters. This research is of great importance for the understanding the interaction involving large halogen-containing molecular clusters. It provides bench mark data for the development of models for the structures and dynamics of weakly bonded molecular complexes.
