摘要

A model of associating multipolar fluid is introduced. It is a one-component fluid with dipole-dipole and anisotropic intracore sticky interaction. The Mayer function of associative sticky interaction consists of the spherically symmetric part and the terms of dipolar and spin-spin symmetry. This model of anisotropic penetrable dipolar hard spheres permits the formation of dimer and higher-order n-mer species. Specific orientation-dependent correlations which result from the association of the monomers influence the structural, dielectric, and thermodynamic properties. The model is analytically solved within the mean spherical approximation. It is shown that the solution reduces to a linear combination of the solutions for the model of overlapping hard spheres of Cummings and Stell. This mapping is similar to that obtained by Wertheim for the dipolar hard-sphere model. [M. S. Wertheim, J. Chem. Phys. 55, 4291 (1971)].
