Competitive Reaction Pathways

在化学学部物理化学项目的这个项目中，南加州大学的Curt Wittig教授将研究基本的化学反应过程。特别是，共振衰变通过竞争的分解途径将被检查使用硝酸根作为原型系统。此外，双共振技术将首次用于涉及弱结合配合物的此类研究。这样就可以明确地识别光引发反应的配合物。硫化羰基-溴化氢和水-一氧化碳等配合物将被视为原型系统。这些研究的目的是在分子水平上更好地理解化学反应。这项工作的结果将是定量的、机械的数据，这些数据将作为测试反应化学理论模型的基准。

In this project in the Physical Chemistry program of the Chemistry Division, Prof. Curt Wittig of the University of Southern California will investigate fundamental chemical reaction processes. In particular, resonances that decay via competing decomposition pathways will be examined using the nitrate radical as a prototype system. Additionally, double resonance techniques will be used for the first time in such investigations involving weakly bound complexes. This will allow the unequivocal identification of the complexes in which the reactions are photoinitiated. Complexes such as carbonyl sulfide-hydrogen bromide and water-carbon monoxide will be considered as prototype systems. The goal of these investigations is a better understanding of chemical reactions on a molecular level. The results of this work will be quantitative, mechanistic data which will serve as benchmarks against which theoretical models of reaction chemistry can be tested.
