Two-Dimensional Heterodyne-Detected VSFG Spectroscopy of Water Molecules at Charged Interfaces
Two-dimensional heterodyne-detected vibrational sum-frequency generation (2D-HD-VSFG) spectroscopy of water at interfaces has been realized for the first time.In the present study, 2D-HD-VSFG spectra were measured at a charged corvette lanyard monolayer / isotopically diluted water interface.In contrast to the 2D-IR spectrum of bulk isotopically di
