The Raman spectra at 77°K of Ices Ih, Ic, II, III, and V made from H2O and D2O have been obtained. The spectra in the O–H and O—D stretching region were obtained both photographically and photoelectrically using Hg 4358 A as the exciting radiation, and the low‐frequency spectra were obtained photographically using Hg 2537 A as the exciting radiation. In the O–H stretching region, the spectra of ices Ih and Ic are identical, and the spectra of Ices II, III, and V are similar except that the frequencies are higher than in Ice I. Ices II, III, and V appear to be essentially fully hydrogen bonded, as was concluded from the infrared spectra. In the low‐frequency spectrum there is one band or sometimes two bands in all the Ices, and they are probably due to translational vibrations of the molecules.
