Second Virial Coefficients for Dimethyl Ether [PDF]
Journal of Chemical & Engineering Data, 2009 Dimethyl ether (DME) is a clean and economical alternative fuel. In addition, it is also an ozone-friendly refrigerant. Burnett measurements were carried out at temperatures from (344 to 393) K and at pressures from (0.055 to 4.015) MPa. A total of 138 experimental points, taken along 15 isotherms and 12 different temperatures, were obtained.

Distribution of the second virial coefficients of globular proteins [PDF]
, 2002 George and Wilson [Acta. Cryst. D 50, 361 (1994)] looked at the distribution of values of the second virial coefficient of globular proteins, under the conditions at which they crystallise. They found the values to lie within a fairly narrow range.

Thermodynamics of d-dimensional hard sphere fluids confined to micropores [PDF]
, 2011 We derive an analytical expression of the second virial coefficient of d-dimensional hard sphere fluids confined to slit pores by applying Speedy and Reiss’ interpretation of cavity space. We confirm that this coefficient is identical to the one obtained

Second Virial Coefficients for Nonspherical Molecules and Their Experimental Measurements [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1991 The virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. The intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a ...
