9313944 Hossenlopp In this project of the Physical Chemistry Program of the Chemistry Division, Prof. J.M. Hossenlopp of Marquette University will investigate the energy disposal patterns in the products of molecular elimination reactions which occur via an asynchronous mechanism. Experiments will be performed on a series of moderate-to-large size organic carbonyl compounds which undergo photochemical eliminations initiated via an intramolecular hydrogen abstraction by the carbonyl oxygen. Polyatomic eliminiation products will be probed by high resolution spectroscopy to provide a detailed view of the dynamics of the carbonyl photodissociation process. The primary goal of this project is to provide a comprehensive framework for interpretation of the photodissociation dynamics of the class of carbonyl photochemical reactions known as the Norrish Type II split. %%% Unimolecular and bimolecular reaction dynamics stand at the forefront of contemporary resarch in physical chemistry. Among the problems considered are how do reactions proceed along different possible and competing pathways. This research project deals with the exploration of the reaction dynamics of polyatomic molecules and their dissociation products produced by photochemical processes. ***

9313944 Hossenlopp在化学系物理化学计划的这个项目中，马奎特大学的J.M.Hossenlopp教授将研究通过异步机制发生的分子消除反应产物中的能量分配模式。实验将在一系列中到大尺寸的有机羰基化合物上进行，这些化合物通过羰基氧分子内的氢提取开始进行光化学消除。多原子消除产物将通过高分辨率光谱学进行探测，以提供对羰基光解过程动力学的详细观察。该项目的主要目标是提供一个全面的框架，用于解释被称为诺里什第二类分裂的一类羰基光化学反应的光解离动力学。%单分子和双分子反应动力学处于当代物理化学研究的前沿。考虑的问题包括反应如何沿着不同的可能和竞争的途径进行。本研究项目是关于多原子分子及其光化学解离产物的反应动力学的探索。***
