Abstract
The Grüneisen constants, as evaluated from compressibility parameters, are redetermined for the alkali metals Li, Na, and K and are determined for Rb and Cs from experimental data of Bridgman, and are shown to be in good agreement with the corresponding values as evaluated from Grüneisen's law. In the cases of Au, Mo, Ta, and Mn, previous work by Slater had shown a large discrepancy between these two evaluations of the Grüneisen constant. The discrepancy is largely removed for Au by a redetermination of the Grüneisen constant from more recent compressibility data of Bridgman. The disagreement persists for Mo (to some degree), and for Ta (where the disparity is large); the results for Mn are inconclusive. A redetermination for Al brings closer agreement than previously between the two evaluations of the constant. The bearing of the results for compressibility parameters on some semiempirical equations of state is indicated.
