Abstract : A new component has been found near 2050/cm in the Raman spectrum or liquid water. This component refers to the two-phonon combination nu sub 2 + nu sub L(where 2 refers to intramolecular bending and L to libration), but the nu sub 2 and nu sub L fundamental involved in this two-phonon component arise from water molecules hydrogen bonded to three rather than to four nearest neighbors. The nu sub 2 bending fundamental from three bonded water molecules was also uncovered. The new Raman data are in excellent agreement with published infrared data and theoretical calculations. Keywords: Water; Raman spectroscopy; Isosbestic point.
