AbstractCHE-0549647Morris/Virginia TechThis research project, supported in the Analytical and Surface Chemistry Program, addresses questions of energy transfer, energy accommodation, and proton transfer reactions in gas-surface interactions at model organic interfaces. Self-assembled monolayers of functionalized thiols on gold surfaces are used as the model interface. Molecular beam scattering and infrared spectroscopic methods are employed to understand these interfacial processes. Professor Morris and his students at Virginia Polytechnic and State University are obtaining this fundamental information about gas-surface interactions, which will be useful in understanding environmental processes involving aerosols, water droplets and volatile organic compounds. The research project also serves as an excellent vehicle for the training of students across a diverse range of communities. With the support of the Analytical and Surface Chemistry Program, Professor Morris is examining the fundamental interactions of gas phase species such as Ne, CH4, NH3 and H2O with model organic interfaces. Self assembled monolayers are used as characterizable model substrates, and molecular beam scattering and infrared spectroscopic methods are used to probe the gas-surface interactions. Fundamental information obtained from this work will be used in environmental and materials contexts, and the research serves as an excellent training ground for a variety of graduate and undergraduate students.

摘要CHE-0549647 Morris/Virginia Tech该研究项目由分析和表面化学项目支持，解决了模型有机界面气体与表面相互作用中的能量转移、能量调节和质子转移反应问题。 功能化的硫醇在金表面上的自组装单分子膜被用作模型界面。 分子束散射和红外光谱的方法来了解这些界面过程。 莫礼时教授和他在弗吉尼亚理工大学及州立大学的学生正取得有关气体与表面相互作用的基本资料，这些资料将有助了解涉及气溶胶、水滴及挥发性有机化合物的环境过程。 该研究项目也是一个很好的工具，为学生在不同的社区培训。 在分析及表面化学课程的支持下，莫礼时教授现正研究气相物种如Ne、CH 4、NH3及H2O与模型有机界面的基本相互作用。 自组装单分子膜被用来作为表征模型基板，分子束散射和红外光谱方法被用来探测气体-表面相互作用。 从这项工作中获得的基本信息将用于环境和材料背景下，研究作为一个很好的培训基地，为各种研究生和本科生。
