On the Calculation of the Pressure Dependence of the Transverse Optical Mode Frequency of Cubic Ionic Crystals

Due to the lack of experimental measurements of the Grüneisen parameter γt = − ∂ In ωt/∂ In V at T → 0 K, this magnitude is calculated for salts of f.c.c. and b.c.c. structures using different models and low and room temperature experimental data. In general, for each salt, similar results are obtai...
