This grant from the Organic Dynamics Program supports the continuing work of Dr. R. Marshall Wilson at the University of Cincinnati. This work will provide new insights into the nature of short-lived intermediates that are produced by irradiation of organic molecules using high-intensity lasers. The experiments that will be carried out by Dr. Wilson are designed to elucidate the reactivity of photochemical intermediates that are produced in multiple photon processes using a unique laser-jet apparatus that greatly enhances the effective light intensity of a focused argon laser beam. High concentrations of reactive intermediates will be generated in the experiments, and Wilson will study their reactions with each other and with trapping agents. The studies will be extended from organic molecules to organometallic species and to transient species adsorbed on silica gel surfaces.

来自有机动力学项目的这笔赠款支持辛辛那提大学R.马歇尔·威尔逊博士的继续工作。这项工作将对有机分子使用高强度激光照射产生的短暂中间体的性质提供新的见解。威尔逊博士将进行的实验旨在阐明在多光子过程中产生的光化学中间体的反应性，这些中间体使用一种独特的激光喷射设备，大大增强聚焦的Ar激光光束的有效光强度。在实验中会产生高浓度的活性中间体，威尔逊将研究它们之间的反应以及它们与捕捉剂的反应。研究将从有机分子扩展到有机金属物种和吸附在硅胶表面的瞬时物种。
