Spectroscopy and Dynamics of Reaction Intermediates

在这个奖项，由化学系的化学结构，动力学和机制（CSDM-A）计划资助，教授玛莎我。宾夕法尼亚大学的莱斯特和她的研究生及博士后研究员同事正在研究大气中活性中间体的化学性质。莱斯特教授和她的团队工作的最终目标是更好地了解对流层的化学，对流层是大气层的最低部分，我们生活和呼吸的地方。 最终，像莱斯特教授这样的研究将导致更好的大气化学模型的发展。 参与该项目的年轻研究人员将从该领域的领导者那里接受先进方法的尖端培训。莱斯特教授和她的团队正在研究的所谓Criegee中间体是臭氧（对流层污染物）与烯烃（一种挥发性有机化合物）反应产生的。 这些有趣的化学物种是大气中烯烃氧化的重要中间体。 莱斯特实验室的实验工作将着眼于：Criegee中间体的解离（单分子和光诱导）;一系列相关化合物的光谱学;以及Criegee中间体与其他大气物种的双分子反应

In this award, funded by the Chemical Structure, Dynamics and Mechanisms (CSDM-A) Program of the Division of Chemistry, Professor Marsha I. Lester of the University of Pennsylvania and her graduate student and post-doctoral researcher colleagues are investigating the chemical properties of reactive atmospheric intermediates. The ultimate goal of the work by Professor Lester and her group is to develop a better understanding of the chemistry of the troposphere, the lowest part of the atmosphere, where we live and breathe. Ultimately, studies like that of Prof. Lester will lead to the development of better models of atmospheric chemistry. The young researchers working on this project will receive sophisticated training in state-of-the art methods from a leader in the field.The so-called Criegee intermediates that Professor Lester and her group are studying are produced in the reaction of ozone (a tropospheric pollutant) with alkenes (a type of volatile organic compound). These interesting chemical species represent important intermediates in the oxidation of alkenes in the atmosphere. The experimental work in the Lester laboratory will look at: the dissociation (unimolecular and photo-induced) of the Criegee intermediates; the spectroscopy of a series of related compounds; and the bimolecular reactions of the Criegee intermediate with other atmospheric species
