Özet

The new modified form of the Pople-Karasz theory of melting of molecular crystals was introduced and applied to investigate the thermodynamics of melting, solid-solid, solid-nematic and nematic-isotropic liquid transitions in the previous papers. In this paper, we give the complete pictures of the transition temperatures and compare with the original Pople-Karasz (PK) theory and its previous modified theories. We also found that the new modified model also gives a much better agreement with available experimental data for the solid-nematic transition than the PK and its previous modified theories by using the different adjustable parameters.
