T2 - Chemical Physics Letters AB - The pair correlation function g(R), giving the probability that the centers of two nonspherical molecules are a distance R apart irrespective of their orientations, has been studied by the Monte Carlo method. The pair potential model studied is of the type uo + ua, where uo is the isotropic Lennard-Jones (12,6) potential and ua is either a dipole-dipole, quadrupole-quadrupole, or anisotropic overlap interaction. Dipolar and quadrupolar forces are found to have a small effect on g(R), whereas anisotropic overlap forces have a large effect.

T2 - AIChE Journal AB - Abstract Perturbation methods relate thermodynamic and transport properties of the system of interest (gas or liquid) to the known properties of some reference system; commonly used reference substances are hard sphere fluids and argon. Developments since 1967 are reviewed for both types of approach, with emphasis on applications to liquid mixtures of practical interest. Calculations for liquid mixtures of simple and complex molecules, gas solubility in liquids, fused salts, electrolytes, solvent extraction systems, and liquid metals are reviewed.

AU - Gray, C.G. AU - Egelstaff, P.A. AU - Ananth, M.S. T2 - Molecular Physics AB - The structure factor S(q) for a fluid of rigid molecules is related to the angular pair correlation function, g(R 12ω1ω2). Several limiting cases of this relation are considered, and its use as a means of obtaining experimental knowledge of orientation correlations is briefly discussed. A first-order perturbation treatment of S(q) is presented, using as a reference a system of molecules with isotropic forces. The theory is used to predict the effect on S(q) of anisotropic dispersion, overlap and multipole (dipole, quadrupole, octopole, and hexadecapole) forces for linear AA, AB and BAB molecules, and also for tetrahedral AB4 molecules and octahedral AB6 molecules. Comparison with experiment is made for liquid bromine and liquid carbon tetrachloride; for both liquids orientation correlations make a substantial contribution to S(q). The theoretical calculations suggest that the most important anisotropic force contribution to S(q) is probably the quadrupolar force in the case of bromine, and the octopolar force in the case of carbon tetrachloride. The models used in this work for the anisotropic dispersion and overlap forces were not able to account for the observed behaviour of S(q) for these two liquids.

AU - Egelstaff, P.A. AU - Gubbins, K.E. T2 - Molecular Physics AB - Abstract Monte Carlo calculations are reported for the radial distribution function g 2(r; λ) of a fluid in which the intermolecular pair potential is [u ref(r) + λu p(r)], u ref(r) being the Weeks-Chandler-Andersen (WCA) reference fluid, and [u ref(r) + u p(r)] being the Lennard-Jones (6, 12) fluid. The calculations are performed for λ values in the range 0 to 1, at the state condition ρσ3 = 0·80, kT/ε = 0·719. It is shown that at high densities the perturbation expansion of g 2(r; λ = 1) about g 2(r; λ = 0) is rapidly convergent, but that the corresponding expansion for y 2(r; λ) = exp [βu(r; λ)] × g 2(r; λ) is not. In addition Monte Carlo estimates of the individual terms that contribute to the first-order perturbation term, (∂g 2/∂λ)λ=0, are presented. It is shown that these terms are individually large, but that (∂g 2/∂λ)λ=0 is small because there is strong cancellation between the various terms. Consequently, the calculation of (∂g 2/∂λ)λ=0 is highly sensitive to the approximation used to evaluate the individual terms. Additional informationNotes on contributorsK.E.

AU - Stell, George T2 - Physical Review A AB - We have investigated the phase behavior that results when an infinitely weak and long-range attractive potential is added to the following hard-core lattice gases: the triangular-lattice gases with exclusions up to first, second, third, and fourth neighbors, and the square-lattice gases with exclusions up to first, second and third neighbors. Three of the systems considered have realistic (i.e., argonlike) phase diagrams, complete with a first-order solid-fluid phase change, a first-order liquid-gas phase change (with a critical point), and a triple point. Three other systems have a first-order solid-fluid phase change. The remaining system has a first-order liquid-gas phase change along with a higher-order transition that is not of the typical solid-fluid type. We find that when the hard-core system has a second-order or first-order phase change to begin with, the addition of the attractive potential spreads the transition out into a first-order phase change with temperature-dependent coexistence densities that bracket the density at which (or density interval over which) the original transition takes place. We also find that the presence or absence of realistic phase behavior for the combined system appears to be dependent upon the shape of the hard core as well as its range.
