Inelastic X-Ray Scattering provides many thermodynamic and elastic properties of minerals, often at high pressures and temperatures comparable to the outer core conditions. Among these quantities, we can list sound velocity (compressional, shear and Debye), elastic constants, vibrational entropy and specific heat, phonon density of states, kinetic energy and phonon dispersion curves. One of the IXS techniques (NRIXS: Nuclear Resonant IXS) is also sensitive to valence and spin transitions, and it provides similar and complementary information like Mössbauer Spectroscopy under extreme conditions, and from nanogram samples.
