Correlation of Third Virial Coefficients to Second Virial Coefficients

Zeitschrift Fur Elektrotechnik Und Elektrochemie, 1989
AbstractA correlation is given for the prediction of third virial coefficients of pure substances and mixtures in terms of second virial coefficients. The substance properties which are needed for the correlation are the critical temperature, the reduced dipole moment, and the parameters for the hard body modelling the molecule.

On-the-Fly Second Virial Coefficients

The Journal of Physical Chemistry B, 2021
A simple but approximate algorithm is described for computing second virial coefficients based on equilibrated molecular configurations that may be generated during any Monte Carlo or molecular dynamics simulation. The algorithm uses simple quadrature based on sampling every binary pair in the configuration and moving their center-center distances from

Second Virial Coefficient of Polar Gases

The Physics of Fluids, 1962
The theoretical expressions for the second virial coefficient, B(T), are derived for the (18–6-3) Stockmayer potential Φ(r)=4ε[(σr)18−(σr)6]−μ2r3g(θ1,θ2,φ),where g(θ1, θ2, φ) = 2 cos θ1 cos θ2 − sin θ1 sin θ2 cos φ, and also according to the (28–7-3) potential.

Second virial coefficient for directed manifolds

Physical Review A, 1991
The second virial coefficient for a D-dimensional polymerized manifold with only mutual repulsive interaction for the same internal D coordinate has been calculated using the perturbative renormalization-group method. This can be carried out to all orders of the perturbative expansion for this model.

GENERAL FORMULA FOR THE SECOND VIRIAL COEFFICIENT

Canadian Journal of Physics, 1961
A simple derivation is given of the quantum mechanical expression for the second virial coefficient in terms of the scattering phase shifts. The derivation does not require the introduction of a quantization volume and is based on the identity R(z)−R0(z) = R0(z)H1R(z), where R0(z) and R(z) are the resolvent operators corresponding to the unperturbed ...

The surface second virial coefficient

Molecular Physics, 1980
The theory of surface virial series is applied to adsorption on a homogeneous solid. Explicit results are given for the Lennard-Jones 12-6 and 9-3 potentials and for the square-well potential with different energies for the solid-gas and gas-gas interaction.

The second virial coefficient of polyelectrolytes

Die Makromolekulare Chemie, 1968
AbstractA critical analysis of the data, obtained by NAGASAWA et al. for the second virial coefficient (A2) determined by light scattering measurements have been carried out for sodium polystyrene sulfonate (NaPSS). The result are analyzed in light of the different theories for the second virial coefficient. Finally, a critical discussion has been made

Interpretation of the Second Virial Coefficient

Journal of Chemical Education, 1999
The second virial coefficient is shown to be related unequivocally to the temperature of Boyle, to the residual volume of a gas, and to the Joule-Thomson effect. From it singular values of the temperature can be determined at which the gas shows apparent ideal behavior in its equation of state only or in specific properties of the ideal gas.
