Molecular Liquids

The essential aspects of a microscopic description of atomic liquids are reviewed, with emphasis on geometric features of the hard sphere model assembly. Before dealing with some microscopic modifications caused by the non‐spherical symmetry of polyatomic molecules, the deviations of molecular liquids from the law of corresponding states are discussed. Then the influences of electric moments are considered in some detail, especially the interference between effects of dipole moments, quadrupole moments and anisotropic molecular shape. Finally, recent perturbation theories for molecules with anisotropic molecular shape are discussed which use hard non‐spherical bodies as reference system.
