The value obtained was then corrected to account for quantum effects that are not considered in the classically computed heat capacity in eq.( ). Specifically, these corrections include estimation of intra-molecular vibrational energies (due to the fact that our model is rigid) and inter-molecular high frequency modes. The values of these correction are reported in the Ref. of Horn et al. The experimental reference data of c p are taken from Ref. Thermal expansion coefficient. We calculated the thermal expansion coefficient α T using the enthalpy-volume fluctuation formula:
