We present the Raman spectra in natural and polarized light of ice Ih monocrystals in the region of the translational frequencies. These spectra are of better quality and higher resolution than previous spectra from monocrystals, and demonstrate the value of the investigation of single crystals by this technique, in spite of the proton disorder. In order to explain the observations we use the model of simultaneous activity of the modes allowed in D 6h symmetry and the modes allowed by thedoi:10.3189/s0022143000033311 fatcat:s4ijo4ob6vb6pedwbbqtu2yv3a
