Ultrafast one and two dimensional infrared studies of complex chemical reactions

在这个由化学部门实验物理化学项目资助的项目中，加州大学伯克利分校的Charles Harris教授和他的学生将使用超快泵浦探针实验和瞬态二维红外光谱研究复杂化学反应的基本步骤。实验工作将与理论建模相结合，以提供对几种原型有机金属反应的详细微观机制的见解，包括C-H和Si-H键激活以及配体取代和歧化中的17和19电子种的反应。这些研究有望证明超快红外技术的能力，以提高我们对有机金属化学的理解，包括催化中的重要反应。该研究还将为研究生和博士后研究员提供时间分辨光谱学和理论化学方面的培训。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Professor Charles Harris and his students at the University of California, Berkeley will study elementary steps in complex chemical reactions using ultrafast pump-probe experiments and transient two-dimensional infrared spectroscopy. The experimental work will be combined with theoretical modeling to provide insights into the detailed microscopic mechanisms of several prototypical, organometallic reactions, including C-H and Si-H bond activation and the reactions of 17- and 19-electron species in ligand substitution and disproportionation. These studies promise to demonstrate the ability of ultrafast infrared techniques to improve our understanding of organometallic chemistry, including reactions of importance in catalysis. The research also will provide training in time-resolved spectroscopy and theoretical chemistry to graduate students and postdoctoral research associates.
