Özet
The specific heat C-V as a function of temperature has been calculated using the quasi-harmonic and mean field approximation for s-triazine close to the transition temperature (T-C=198 K). Using the parameters for the shear strain angle (order parameter) fitted to the observed Raman frequencies of the four bands, the specific heat C-V is calculated from the free energy of s-triazine. The calculated C-V values show no anomaly in comparison with the experimentally observed C-P which exhibits a sharp peak near T-C in s-triazine.
