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.

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。本课题是在美国物理化学实验计划的资助下，在F。弗莱明克里姆在威斯康星州-麦迪逊大学，是一个协调的研究化学动力学的液体和气体，以确定和理解的重要相似之处和两者之间的严重差异。重点是比较两种情况下振动激发对双分子反应的影响，并利用振动激发来控制反应的进程。这些实验遵循振动激发复合物内和振动激发溶质分子和复合物之间的反应。在分子束中对相同反应的单次碰撞研究通过观察振动激发的影响而不受周围溶剂的影响提供了一个比较点。这些观察描绘了控制化学反应的要求，并对理论描述进行了精辟的检验。本项目的基础科学为本科生和研究生提供了为工业、政府和企业的科技企业做出贡献所需的经验和技能，这一点已被过去的学生的历史所证明。新的机会，旨在整合研究，教学和学习更完全地在威斯康星州-麦迪逊大学使它有可能，这个研究项目将激励开始科学家和先进的学生对各种专业目标更有效。该项目的首席研究员还与全国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参与。
