和频振动光谱技术已发展成为研究表面和界面的重要技术。它可以原位探测掩埋的界面，并提供分子水平的结构信息，如各种化学部分的存在，定量的分子官能团取向，和时间依赖的动力学或动力学在这样的界面。本文重点介绍了SFG的这三个最重要的优点，并综述了SFG在高分子材料和生物分子界面研究方面的一些最新进展。结果表明，SFG技术可以在原位和真实的时间内提供重要的界面结构信息，这是其它表面敏感分析技术难以获得的。
Sum frequency generation (SFG) vibrational spectroscopy has been developed into an important technique to study surfaces and interfaces. It can probe buried interfaces in situ and provide molecular level structural information such as the presence of various chemical moieties, quantitative molecular functional group orientation, and time dependent kinetics or dynamics at such interfaces. This paper focuses on these three most important advantages of SFG and reviews some of the recent progress in SFG studies on interfaces related to polymer materials and biomolecules. The results discussed here demonstrate that SFG can provide important molecular structural information of buried interfaces in situ and in real time, which is difficult to obtain by other surface sensitive analytical techniques.
