中文摘要
该项目是一项为期三年的实验室研究,涉及臭氧与烯烃的反应以及过氧基与对流层低层的氮氧化物的反应。这项研究的重点是确定和表征短命中间体(Criegee中间体)在这些反应中的作用。为了进行这项研究,P.I.正在建造一套具有红外和紫外/可见光光谱的流动反应堆系统。预计该项目将有助于更好地了解大气氧化形成对流层臭氧的机制。
英文摘要
This project is a three-year laboratory study involving the reactions of ozone with alkenes and the reactions of peroxy radicals with nitrogen oxide in the lower troposphere. This study is focused on identifying and characterizing the role of short-lived intermediates (Criegee intermediates) in these reactions. The P.I. is in the process of building a system of flow reactors with infrared and ultraviolet/visible spectroscopy to carry out the study. This project is expected to contribute to a better understanding of atmospheric oxidation mechanisms leading to the formation to tropospheric ozone.
