Heterodyne-Detected Sum Frequency Generation(HD-SFG)spectroscopy has been newly developed for spectroscopic analyses of liquid surfaces. HD-SFG can provide very high quality data that cannot be given by existing SFG. HD-SFG allows one for the first time to perform quantitative analyses of liquid surfaces by directly providing spectroscopic data proportional to the density of surface molecules. HD-SFG can also indicate "up" versus "down" alignment of surface molecules very clearly by the sign of data. It is expected that HD-SFG will become a standard method for spectroscopic analyses of liquid surfaces.
