title: Temperature and pressure dependence of the Raman frequency shifts near the melting point in ice I.
abstract: This study examines the validity of the spectroscopic modification of the Pippard relations for the hexagonal ice (ice I) close to the melting point. A linear variation of the specific heat CP with the frequency shifts EQUATION: SEE TEXT is obtained for ice I. This linearity is also obtained between thermal expansivity alphaP and the frequency shifts EQUATION: SEE TEXT close to the melting point in this crystal.
