Vibrationally Controlled Reactions of Complexes in Liquids and Gases

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目由实验物理化学项目支持，在威斯康星大学麦迪逊分校F. Fleming Crim教授的实验室进行，是一项液体和气体化学动力学的协调研究，以确定和理解两者之间的重要相似之处和严重差异。重点是比较两种情况下振动激励对双分子反应的影响，并利用振动激励控制反应过程。这些实验既跟踪振动激发配合物内部的反应，也跟踪振动激发溶质分子与配合物之间的反应。对分子束中相同反应的单次碰撞研究提供了一个比较点，通过观察振动激发的影响而不考虑周围溶剂的复杂性。这样的观察描述了控制化学反应的要求，并对理论描述进行了精辟的检验。这个项目中的基础科学为本科生和研究生提供了为工业、政府和学术界的科技事业做出贡献所需的经验和技能，正如过去学生的历史所证明的那样。威斯康星大学麦迪逊分校旨在将研究、教学和学习更全面地结合在一起的新机会，使这项研究项目有可能激励初级科学家，并更有效地将高级学生带向各种专业目标。该项目的首席研究员还与全国的教育和政策相关团体合作，他的持续研究活动促进和加强了这种参与。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This project, supported by the Experimental Physical Chemistry Program and conducted in the laboratory of Professor F. Fleming Crim at the University of Wisconsin - Madison, is a coordinated study of chemical dynamics in liquids and gases in order to identify and understand the important similarities and acute differences between the two. The key aspect is comparing the influence of vibrational excitation on bimolecular reactions in the two settings and using vibrational excitation to control the course of the reactions. These experiments follow reactions both within vibrationally excited complexes and between vibrationally excited solute molecules and complexes. Single collision studies of the same reactions in a molecular beam provide a point of comparison by observing the influence of vibrational excitation without the complication of the surrounding solvent. Such observations delineate the requirements for control of chemical reactions and test theoretical descriptions incisively.The fundamental science in this project gives undergraduates and graduate students the experience and skills required to contribute to the scientific and technical enterprise in industry, government, and academe, as proven by the history of past students. New opportunities designed to integrate research, teaching, and learning more completely at the University of Wisconsin - Madison make it likely that this research project will inspire beginning scientists and carry advanced students toward a variety of professional goals even more effectively. The principal investigator on this project also works with both education and policy related groups nationally, a participation facilitated and enhanced by his continuing research activities.
