Calculation of the specific heat using the Raman frequency shifts for the solid I-II transition in benzene

The specific heat CP due to the contributions of the six lattice modes, increases with the increasing temperature at constant pressures (P = 0 and 0.1 GPa) and it decreases with increasing pressure (T = 300 K), as expected. Our calculated CP values can be compared with the experimental measurements for the solid I-II transition in benzene.
