The dynamic behaviour of the modified Pople–Karasz model is studied by the direct relaxation method and the path probability method. First the equilibrium behaviour of the model is given briefly in order to understand the dynamic behaviour. Then the direct relaxation method, which is based on...

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...

A new modified model that combines the modified models of Chandrasekhar et al. with those of Keskin and Özgan, which are based on the Pople–Karasz theory, is applied to study the thermodynamics of melting and solid–solid transitions of molecular crystals. The thermodynamic properties of the...
