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...

| Sumario: | 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 obtained with all models, being slightly larger those given by the shell model. When low temperature data are used the values are similar to the room temperature experimental data available. Copyright © 1985 WILEY‐VCH Verlag GmbH & Co. KGaA |
