Abstract: Over the last decade, infrared-visible sum-frequency
generation has been developed into a powerful vibrational spectroscopic
technique, especially for surface studies. We give here a brief review
of the technique and a few recent applications of the technique to liquid
and polymer surfaces. We also describe how the technique has found unique
applications in our studies of surface melting of ice, ferroelectric
ice films, and molecular chirality in chiral liquids. Doubly resonant
sum-frequency generation as surface-specific two-dimensional spectroscopy
