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

9633002 Wodtke 该项目将研究在模拟平流层上层发生的条件下高度振动激发的分子氧的命运。 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，特别是假设高度振动激发的（v 26）氧与其他氧分子反应形成臭氧。 通过一系列实验室实验，首席研究员将研究导致平流层臭氧形成的反应过程。 PI 将建造一个涉及飞行时间质谱的新实验装置，该装置将被配置和优化，用于检测高度振动激发的氧反应物的化学反应产物。 该项目的结果将推进对平流层中分子氧的化学和物理性质的了解，并加深对影响平流层臭氧浓度因素的了解。 *** ATM-9633002
