Production and Destruction Chemistry of Highly Excited Oxygen in the Stratosphere

[633002] Wodtke这个项目将研究高振动激发的分子氧在模拟平流层上层条件下的命运。该项目的目标是进一步了解该地区臭氧的形成和破坏过程，特别是高振动激发（v 26）氧与其他氧分子反应中臭氧的假设形成。通过一系列的实验室实验，PI将调查导致平流层臭氧形成的反应过程。PI将建造一个新的实验装置，其中包括飞行时间质谱，该装置将被配置和优化，用于检测高振动激发氧反应物的化学反应产物。该项目的结果将推进关于平流层中存在的分子氧的化学和物理性质的已知知识，并提供对影响平流层臭氧浓度的因素的更多了解。* * * atm - 9633002

9633002 Wodtke This project will investigate the fate of highly vibrationally excited molecular oxygen under conditions which are intended to simulate those occurring in the upper stratosphere. The goal of the project is to further understand ozone formation and destruction processes in this region, in particular, the hypothesized formation of ozone from the reaction of highly vibrationally excited (v 26) oxygen with other oxygen molecules. Through a series of laboratory experiments, the PI will investigate reaction processes that lead to stratospheric ozone formation. The PI will construct a new experimental apparatus that involves Time-of-Flight Mass Spectroscopy that will be configured and optimized for the detection of chemical reaction products of highly vibrationally excited oxygen reactant species. Results from the project will advance what is known concerning the chemical and physical properties of molecular oxygen present in the stratosphere, and provide increased understanding of factors influencing stratospheric ozone concentrations. *** ATM-9633002
