Abstract: In this study we present new experimental heat capacity data of solid and liquid phase of CsF covering the temperature range from 5 K to 1400 K. The low temperature data were obtained by adiabatic calorimetry and compared with the theoretical heat capacity computed from ab initio anharmonic crystal approximation. The absolute entropy at 298.15 K determined based on the presented results is 93.60 J/K/mol. The high temperature heat capacity was measured using a drop calorimeter and the data for the solid phase revealed significant excess properties. The data for the liquid phase were correlated with the molecular dynamic simulation obtaining a good agreement. The recommended molar heat capacity of the CsF solid phase is: Cp=24.291 + 6.4607E-2 T +589981/T2
