The reproduced and experimental heat capacities of all samples except polycaprolactone and poly(3,3-bis(chloromethyl)oxetane) agreed within ☒.5%, and the errors for polycaprolactone and poly(3,3-bis(chloromethyl)oxetane) were within ±4.0%. We thus reproduced the measured heat capacities of eight polyester and five poly(oxide) polymer solids with a carbon and oxygen backbone. In this combination of equations, the absolute value of the heat capacity was obtained with only three fitting parameters. The heat capacity contributing to the skeletal vibration can be expressed by one- and three-dimensional Tarasov equations, and the contribution of the group vibration can be determined by substituting the absorption frequency obtained from infrared absorption measurements for the frequency value in the Einstein equation. Furthermore, the estimated heat capacity was corrected by the difference between the heat capacities measured at constant pressure and at constant volume. The frequencies of the skeletal and group-vibration modes were calculated by the Tarasov and Einstein equations, respectively. We evaluated the absolute values of the heat capacity of polymer solids composed of polyesters and poly(oxide)s below the glass transition temperature.
