Aqueous Surfaces: Probing their Molecular and Adsorptive Properties with Experiment and Theory

本研究项目考察了自由水界面的结构、与疏水层接触的水表面、存在分子离子和含硫吸附剂的水界面，以及油/水界面上生物分子物种的相互作用。在分析和表面化学项目的支持下，里士满教授和她在俄勒冈大学的合作者正在对这些复杂而重要的系统进行实验和计算研究。在这些研究中，振动和频率谱结合分子动力学模拟，获得了液/液和液/气界面的结构和动力学信息。在这些研究中获得的基本理解在各种化学过程、环境和生物背景下都是重要的。在分析和表面化学项目的支持下，Richmond教授正在研究水界面的结构和动力学。通过和频率生成和分子动力学模拟获得的振动光谱信息提供了对这些重要界面的理解。这项工作的结果与涉及水界面的广泛的环境、化学和生物过程有关。

This research project examines the structure of the free aqueous interface, water surfaces in contact with hydrophobic layers, the aqueous interface in the presence of molecular ions and sulfur-containing adsorbates, as well as the interaction of biomolecular species at the oil/water interface. With the support of the Analytical and Surface Chemistry Program, Professor Richmond and her collaborators at the University of Oregon are carrying out experimental and computational studies of these complex and important systems. Vibrational sum frequency spectroscopy, in combination with molecular dynamics simulations, is used to obtain structural and dynamic information about the liquid/liquid and liquid/vapor interface in these studies. The fundamental understanding obtained in these studies is of importance in a variety of chemical process, environmental, and biological contexts.With the support of the Analytical and Surface Chemistry Program, Professor Richmond is examining the structure and dynamics of aqueous interfaces. Vibrational spectroscopic information obtained using sum frequency generation and molecular dynamics simulations provide an understanding of these important interfaces. Results of this work are relevant to a broad range of environmental, chemical, and biological processes involving the water interface.
