Fig. 14.16. Comparison between the temperature dependence of the specific heat for CM on cooling (A) and heating (x). The inset shows the low-temperature specific heat on a magnified scale and the change in slope near 50 K is indicated explicitly [14.146].

in Fig. 14.17 [14.150]. The model predicts a first-order phase transition at T0i with agreement obtained between theory and experiment regarding the latent heat and entropy change at 7}„ (see §7.1.5).

Upon further cooling of crystalline Qq, a second anomaly in Cp(T) is observed, with a peak in the specific heat at 165 K [14.146], This peak in the specific heat is identified with a Schottky anomaly associated with the
