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 C-P with the frequency shifts 1/nu(partial derivative nu/partial derivative P)(p) is obtained for ice I. This linearity is also obtained between thermal expansivity alpha P and the frequency shifts (partial derivative nu/partial derivative P)(T) close to the melting point in this crystal.
