In this project supported by the Experimental Physical Chemistry Program, Professor Charles B. Harris of the University of California, Berkeley and his research group will develop novel two-dimensional infrared (2D IR) techniques for the study of transition states in solution. The reactions for study include ligand fluxionality, photoinduced ligand dissociation, and intramolecular electron transfer in mixed-valence complexes. The compounds under study are model systems with well characterized structures and chemistry, but whose molecular dynamics are not well known. The experiments in this project involve the development of new spectroscopic tools that can reveal unprecedented information that will have a fundamental impact on our understanding of chemical reaction dynamics in solution. Additionally, this research will benefit from a multi-faceted approach involving not only experimental molecular spectroscopy but also synthesis and theory. Students (both graduate and undergraduate) as well as postdoctoral scholars will benefit from this multi-disciplinary research environment. Finally, the Harris group is engaged in a variety of community outreach activities that promote a broader public understanding and appreciation for chemistry and science in general.

在这个由实验物理化学计划支持的项目中，加州大学伯克利分校的Charles B. Harris教授和他的研究小组将开发新的二维红外（2D IR）技术来研究溶液中的过渡态。研究的反应包括配体的流动性、光诱导配体解离和混合价配合物中的分子内电子转移。所研究的化合物是具有良好结构和化学特征的模型体系，但其分子动力学尚不清楚。该项目的实验包括开发新的光谱工具，这些工具可以揭示前所未有的信息，这些信息将对我们对溶液中的化学反应动力学的理解产生根本性的影响。此外，这项研究将受益于多方面的方法，不仅包括实验分子光谱，而且包括合成和理论。学生（包括研究生和本科生）以及博士后学者将受益于这种多学科的研究环境。最后，哈里斯小组参与了各种各样的社区外展活动，以促进更广泛的公众对化学和科学的理解和欣赏。
