✦ Synopsis

From Brillouin spectra of tetrachloromethane, benzene and cyclohexane measured between 283.15 K and 343.15 K, and carefully re-evaluated data for the heat capacities at constant pressure CP, and constant volume C,,, the vibrational contribution to CV was determined and compared with calculated values obtained from the Planck-Einstein relation. Utilizing perfect gas state heat capacity data, the residual heat capacity Ci was determined and subsequently used to present an estimate for the residual rotational heat capacity (external rotation).
