Abstract

A procedure for calculating Debye heat capacity values, usually obtained by means of series solutions or by numerical integration, has been developed. The procedure is based on the simpler analytical form of the Einstein heat capacity model. By replacing ΘE with a simple function of T/ΘD, the Einstein model can predict heat capacity values which agree with Debye model predictions with an average percentage error of 0.39% over a temperature range of 0.075 ⩽ T/ΘO ⩽ 12. As the lower temperature limit rises, the agreement is even better. This procedure is particularly useful in analysing experimental data which require many heat capacity calculations over wide ranges of temperature.
