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

该研究项目检查了自由水界面的结构，与疏水层接触的水表面，分子离子和含硫吸附物存在下的水界面，以及生物分子物种在油/水界面的相互作用。 在分析和表面化学项目的支持下，俄勒冈州大学的里士满教授和她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，振动和频光谱与分子动力学模拟相结合，用于获得有关液/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是在各种化学过程，环境和生物contextual.With分析和表面化学程序的支持下，教授里士满正在研究水界面的结构和动力学的重要性。 使用和频产生和分子动力学模拟获得的振动光谱信息提供了这些重要的接口的理解。这项工作的结果是相关的一个广泛的环境，化学和生物过程，涉及水界面。

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.
