| Summary: | 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.

He then received his MS degree in physics from the Institute of Physics, Chinese Academy of Sciences in 1991. After he worked in the Institute of Physics for 2 years as a research scientist, he went to the Department of Chemistry at the University of California at Berkeley in 1993. He received his PhD degree in 1998, advised by Prof. Herbert Strauss. He then worked as a postdoctoral research fellow in Prof. Gabor Somorjai's group at Berkeley. He started his own research group in 2000 at the University of Michigan. Currently, he is a professor of Chemistry there. His research is to understand the molecular structures of polymers and biological molecules at interfaces. John Myers received a BS degree in Biochemistry from Bradley University in 2009 and a MS degree in Analytical Chemistry from Miami University in 2011. He is currently a graduate student in the Department of Chemistry at the University of Michigan advised by Prof. Zhan Chen. His current research focuses on nonlinear optical spectroscopic studies of polymer surfaces and buried interfaces. Chi Zhang is currently a PhD candidate in Chemistry at the University of Michigan, advised by Prof. Zhan Chen. He earned his BS and MS in Opto-electronics at Tianjin University in 2006 and 2009. His work now focuses on molecular level understanding of interfaces involving polymers, and developing nonlinear spectroscopic and microscopic techniques for material and biological study.
