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.

使用反射吸收红外方法的表面振动光谱是该研究项目的重点，该项目由分析和表面化学计划支持。 芝加哥伊利诺伊大学的Trenary教授及其学生将使用振动光谱法确定吸附物种的身份和结构。 正常的模式分析将应用于该光谱数据的解释，实现振动带的分配以及确定吸附物种的结构参数。 这些方法将这些方法应用于铜表面上的甲氧基，以及在铂表面上的异氰化物和相关部分的应用是感兴趣的主要系统。 这项工作的结果将在表面IR的常规使用中广泛应用以表征反应过程。 通过开发正常模式分析方法，将表面红外光谱作为常规分析工具的使用将是该研究项目的主题。 为了理解表面上的反应过程，必须鉴定并在结构上鉴定出吸附的反应物，产物和中间体。 正常的模式方法将使表面化学界通常可用此特征。
