Abstract

The specific heat C-p is calculated as a function of temperature using the observed Raman frequency shifts of the six lattice modes at constant pressures of 0 and 0.1 GPa for the solid I-II transition in benzene. This calculation is performed using the volume data through the mode Grfineisen parameter of each lattice mode which we determined as functions of temperature and pressure. The specific heat C-p is also calculated as a function of pressure at room temperature using the Raman frequency shifts of those phonon modes studied.
