INTEGRAL-EQUATION APPROXIMATIONS FOR DIPOLAR FLUIDS

The linearized and quadratic hypernetted-chain approximations are solved for fluids of dipolar hard spheres and Stockmayer particles. The density and dipole moment dependence of the pair correlation function, dielectric constant and some thermodynamic properties is investigated. Comparisons with new Monte Carlo results show that, at low density, the linearized theory gives a very poor description of the pair correlations. The quadratic approximation, however, is found to be excellent for all densities and dipole moments considered. © 1979 Taylor & Francis Group, LLC.
