Professor Parson is supported by a grant from the Experimental Physical Chemistry Program to study reactions of atoms and molecules by crossing one molecular beam with another. The products are to be detected by chemiluminescence and laser-induced fluorescence so that the energy states in which the products are formed can be determined. These studies will map out the elementary steps which make up the chemical reaction. Molecular beam studies of reactions of Group VA atoms, clusters, and hydrides with halogens and oxidizers will be carried out. Products will be detected by electronic chemiluminescence or laser-induced fluorescence, and the Group VA molecular beam composition will be manipulated by a combination of thermal, electric discharge, and photodissociation techniques. The results should be relevant to understanding mechanisms in bulk reaction systems. In addition to identifying important elementary steps, single collision studies will provide information about the disposal of reaction energy in products. By accessing different potential surfaces with variable collision energy, major characteristics of those surfaces can be inferred.

帕森教授得到了实验物理化学计划的资助，通过分子束交叉来研究原子和分子的反应。产物将通过化学发光和激光诱导荧光来检测，从而确定产物形成的能态。这些研究将绘制出构成化学反应的基本步骤。将进行VA族原子、团簇和氢化物与卤素和氧化剂反应的分子束研究。产品将通过电子化学发光或激光诱导荧光检测，而VA族分子束的组成将通过热、放电和光解技术的组合来操纵。结果应该与理解体反应系统的机制有关。除了确定重要的基本步骤外，单次碰撞研究将提供有关产品中反应能量处置的信息。通过访问具有可变碰撞能量的不同潜在表面，可以推断出这些表面的主要特征。
