在这个由分析和表面化学项目支持的研究项目中，科恩教授将利用二次谐波产生来研究几个重要界面系统的结构和动力学。液-液界面的研究将把SHG方法与标准表面张力和电化学测量相结合，以确定界面上的分子吸附和结构。自组装的烷基膦酸锆层也将使用SHG和振动光谱方法进行检查，以确定界面层内的分子取向。在这些研究中获得的分子结构信息将用于设计和控制界面的宏观性质。该研究项目将结合最先进的非线性光学方法，如二次谐波产生，来探测几个技术上重要的界面系统的详细分子结构。液-液界面，自组装的碱性磷酸锆单层和电化学表面将被检查。本研究结果将为界面系统的合理设计提供必要的理解。

The use of second harmonic generation will be developed by Professor Corn to investigate the structure and dynamics of several important interfacial systems in this research project supported by the Analytical and Surface Chemistry Program. Studies of liquid-liquid interfaces will combine the SHG method with standard surface tension and electrochemical measurements to determine molecular adsorption and structure at the interface. Self assembled zirconium alkyl phosphonate layers will also be examined using SHG and vibrational spectroscopic methods, to determine molecular orientation within the interfacial layer. The molecular structural information obtained in these studies will be used to design and control the macroscopic properties of the interface. %%% This research project will combine state of the art non-linear optical methods such as second harmonic generation to probe the detailed molecular structure of several technologically important interfacial systems. Liquid-liquid interfaces, self-assembled zirconium alkly phosphonate monolayers, and electrochemical surfaces will be examined. The results of this research will provide the understanding essential to the rational design of interfacial systems.
