ResumoThe heat capacity of VO2 was remeasured both above and below the transition temperature range of 330 – 345 K. For 150 < T < 320 K the results could be fit to the standard Debye theory with a Debye temperature θD = 750 K; for 360 < T < 720 K no Debye temperature could be assigned to the data, which exceeded the equipartition value for Cv above 580 K. The enthalpy of transition was found to be 1.12 k cal/mole VO2.
