Abstract

The correlation between the structure and thermodynamic properties of minerals has long been considered fundamental. Besides the first-law functions, it is possible to calculate entropy and free energy for a pure ideal crystal if the vibrational properties are taken into account. These calculations imply the precise evaluation of spectroscopic data (Raman, IR, phonon dispersion curves) and allow good estimates of elastic properties and atomic displacement parameters.
