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.

Second virial coefficient of the interacting anyon gas

Physical Review B, 1994
Arovas and co-workers, in their well-known paper on the statistical mechanics of anyons [D. P. Arovas, R. Schrieffer, F. Wilczek, and A. Zee, Nucl. Phys. B251, 117 (1985)], found that the second virial coefficient of a two-dimensional gas of free anyons exhibits nonanalytic behavior as the statistical parameter is varied in the neighborhood of the Bose

The second virial coefficient of benzene

Recueil des Travaux Chimiques des Pays-Bas, 1951
AbstractA one‐parameter family of curves for the second virial coefficient of benzene as a function of temperature is computed from caloric precision measurements.The formulae given by Hirschfelder c.s. and by van Laar for B(T) are compared with this experimental temperature relation.
