Correlations between Raman frequency shifts and the thermodynamic quantities close to the melting point in D₂O ice

Abstract

The Raman frequency shifts ( )of the translational mode are correlated to the specific heat C p and to the thermal expansivity α p , respectively, in D 2 O ice. Close to the melting point, they correlate linearly, from which the values of the slopeP T are in very good agreement with the experimentally obtained value in this crystalline system.

Analysis of Heat Capacity and Glass Transition in Amorphous Ice

“…Since ice exhibits a very rich phase diagram, various experimental techniques have been used to investigate the phase boundaries, as we have reviewed in our earlier work. 9 A complete T-P phase diagram of ice has been given by Fletcher 10 and a more recent one 11 has also been obtained experimentally. Calculations on various phase boundaries in a phase diagram of ice have been performed using theoretical models.…”
