The heat capacity of the dichalcogenide: tungsten ditelluride, WTe2, was measured over the temperature range 5.5a phase transition is not present.However, an anomalous rise in the molar heat capacity C_p,m occurs in the region 92m = (0.10+/-0.02)*R.The anomaly coincides with the temperature range where all the translational, librational, and internal vibrational modes become fully excited.The electronic molar heat capacity Tγ_m = (5.99+/-1.83)mJ*K^-1*mol^-1 and for the lattice, the Debye characteristic temperature Θ_D = (133.8+/-0.6) K.Standard molar thermodynamic functions are presented at selected temperatures from 5 K to 335 K.
