\(\gamma = \frac{\alpha_V}{x_T c_V\rho}\), where \(\alpha_V\) is the cubic expansion coefficient, \(x_T\) is isothermal compressibility, \(c_V\) is specific heat capacity at constant volume, and \(\rho\) is mass density.

\(\gamma\)

"Gruneisen Parameter" named after Eduard Grüneisen, describes the effect that changing the volume of a crystal lattice has on its vibrational properties, and, as a consequence, the effect that changing temperature has on the size or dynamics of the lattice.
