对金属电极和自组装单分子膜(SAM)修饰电极的界面结构进行了全面的光谱和电化学研究，形成了本研究的重点。在分析和表面化学计划的支持下，表面拉曼光谱将用于原位探测金属电极，并在电位控制下出现。此外，还将使用超高真空方法来制备模拟这些电化学界面行为的模型系统。表面拉曼光谱以及其他表面光谱探针将用于表征这些模型体系。还将使用这些方法来探测由有机覆盖层修饰的电极表面。对电化学界面结构的详细了解对许多电化学系统和传感器的设计至关重要，从燃料电池到环境监测设备。这里支持的工作开发并将这些界面的结构特征的方法应用于一系列控制良好的模型系统。从这些研究中获得的信息在电化学的广泛技术应用中将是无价的。

Comprehensive spectroscopic and electrochemical investigations of the interfacial structure of metal electrodes and self assembled monolayer (SAM) modified electrodes form the focus of this research project. In work supported by the Analytical and Surface Chemistry Program, surface Raman spectroscopy will be used to probe metal electrodes in situ and emersed under potential control. In addition, ultra high vacuum methods will be used to prepare model systems which mimic the behavior of these electrochemical interfaces. Surface Raman spectroscopy, as well as other surface spectroscopic probes, will be used to characterize these model systems. Electrode surfaces modified by organic overlayers will also be probed using these methods. A detailed understanding of the structure of electrochemical interfaces is crucial to the design of many electrochemical systems and sensors, ranging from fuel cells to environmental monitoring devices. The work supported here develops and applies methods for the structural characterization of these interfaces to a range of well controlled model systems. The information gained from these studies will be invaluable in a wide range of technological applications of electrochemistry.
