ACOUSTIC VELOCITIES IN ICE Ih, II, III, V AND VI, BY BRILLOUIN SPECTROSCOPY

R. Gagnon , H. Kiefte , M. Clouter , E. Whalley

The technique of high resolution Brillouin spectroscopy has been used to determine longitudinal and transverse acoustic velocities in isotropic polycrystalline aggregates of ice Ih, II, III, V and VI. The data can be explained on the basis of a classification scheme, founded on knowledge of hydrogen-bonding. The bulk moduli (±5%) derived from the velocity data, for ice II, III, V and VI are 138.9, 98.7, 141.9, and 181.4 kbar respectively. Also, the density has been measured using a new technique.
