Photographic Raman spectra were obtained at shifts to ca. 7000 cm(-1) for pure water and for a saturated aqueous solution of NaCl using argon ion laser excitation. Raman spectra were also obtained photoelectrically for H2O and D2O between ca. 2500 and ca. 7000 cm(-1) using 248-nm excimer laser excitation and boxcar detection. Overtone and combination assignments are presented for H2O and D2O. The first IR OH-stretching overtone from water occurs 215 cm(-1) above the first Raman OH-stretching overtone because the IR overtones are dominated by asymmetric stretching. The second OH-stretching Raman overtone from water is estimated to occur near 10,020+/-20 cm(-1), with 9950 cm(-1) as a lower limit.
