Infrared Spectroscopic Studies of the Structure and Reactions of Molecules on Metal Surfaces

表面振动光谱，使用反射吸收红外方法，是由分析和表面化学计划支持的这个研究项目的重点。 Trenary教授 和他在芝加哥的伊利诺伊大学的学生们 使用振动光谱确定吸附物质的身份和结构。 正常模式分析将被应用到解释这一光谱数据，使分配的振动带，并确定吸附物种的结构参数。 将这些方法应用于铜表面上的甲氧基中间体以及铂表面上的异氰化物和相关部分是主要的感兴趣的系统。 这项工作的结果将看到广泛的应用在日常使用的表面红外表征反应过程。 作为常规分析工具的表面红外光谱的使用将通过本研究项目的主题的正常模式分析方法的开发而实现。 为了了解表面上的反应过程，吸附的反应物，产物和中间体必须进行鉴定和结构表征。 正常模式方法将使这种表征常规提供给表面化学界。

Surface vibrational spectroscopy, using reflection absorption infrared methods, is the focus of this research project supported by the Analytical and Surface Chemistry Program. Professor Trenary and his students at the University of Illinois at Chicago will determine the identity and structure of adsorbed species using vibrational spectroscopy. Normal mode analysis will be applied to the interpretation of this spectroscopic data, enabling assignment of vibrational bands, and determination of structural parameters for the adsorbed species. The application of these methods to the methoxy intermediate on copper surfaces, and to isocyanide and related moieties on platinum surfaces are the primary systems of interest. The results of this work will see broad application in the routine use of surface IR to characterize reaction processes. The use of surface infrared spectroscopy as a routine analytical tool will be enabled by the development of normal mode analysis methods which are the subject of this research project. In order to understand reaction processes on surfaces, adsorbed reactants, products, and intermediates must be identified and structurally characterized. Normal mode methods will make this characterization routinely available to the surface chemistry community.
