Empirical Equations Of State

Both phonon dispersion and anharmonicity contribute to the thermo-physical properties of solids in such a way that serious mistakes can be made, if these effects are not taken into account in the realization of semi-empirical equations of state (EOS) from limited experimental data sets. These effects are illustrated in comparisons of EOS data for different types of solids.
