Abstract:
Infrared-visible sum-frequency generation has been developed into a powerful vibrational spectroscopic tool to study surfaces and interfaces. It is highly surface-specific and sensitive in media with inversion symmetry, and therefore has found many unique applications in areas that have not been well explored. We discuss here a few examples including liquids and polymers. We show that the observed surface vibrational spectra allow us to obtain information about surface structures of liquids and polymers. While such information is often qualitative, it is possible in some better prepared cases to deduce quantitative details about molecular orientation and alignment at the surface.
