Molecular Structure and Adsorption Dynamics at Liquid/Liquid Interfaces

全内反射振动和频光谱用于探测这些研究中的液/液界面的分析和表面化学程序的支持。 俄勒冈州大学的里士满教授和她的同事们正在探测水/碳氢化合物界面处的水的氢键。 他们还研究了烷基表面活性剂分子在油/水界面的结构和动力学，提供了有关吸附在界面上的这些分子的构象变化的重要信息。 这为理解离子和分子跨膜和其他生物学重要结构的传输提供了基础。 利用里士满教授实验室开发的非线性光谱学方法，油/水界面分子的结构和动力学形成了本研究项目的重点。 了解分子在这个界面上的排列和运动对于许多重要的生物过程的运作非常重要，包括呼吸和体内营养物质的运输。 这项研究提供了对这些重要过程的概念性理解，以及研究它们所需的工具。

Total internal reflection vibrational sum frequency spectroscopy is used to probe the liquid/liquid interface in these studies supported by the Analytical and Surface Chemistry Program. Professor Richmond and her colleagues at the University of Oregon are probing the hydrogen bonding of water at the water/hydrocarbon interface. They are also investigating the structure and dynamics of alkyl surfactant molecules at the oil/water interface, providing important information about the changing conformation of these molecules adsorbed at the interface. This provides the basic groundwork for understanding ion and molecular transport across membranes and other biologically important structures. Using methods of non-linear spectroscopy developed in Professor Richmond s laboratories, the structure and dynamics of molecules at the oil/water interface form the focus of this research project. Understanding the arrangement and motion of molecules at this interface is important to the operation of many vital biological processes, including respiration and transport of nutrients in the body. This research provides both the conceptual understanding of these important processes, as well as the tools needed to study them.
