the calculation of the second and third molar virial coefficients
1]), and the virial coefficients
are functions of temperature only, and equations for their calculation are given in Hyland and Wexler (1980).
Since catalytic surface temperatures are much larger than the characteristic Lennard-Jones temperature given by Equation (23), quantum corrections to second virial coefficients
are neglected because these corrections are only significant below dimensionless temperatures T * = 0.
The closing chapters list enthalpy changes in polymer solutions at elevated pressures, PVT data of some selected polymers and their solutions, and second virial coefficients
The CGS-3 can perform simultaneous analysis of both static and dynamic light-scattering parameters, resulting in better and faster measurement of particle size, molecular weight, diffusion coefficients and virial coefficients
A short paper presented at the 1989 Prague meeting describes qualitatively the origin of the difference in the second virial coefficients
of H2O and D2O steam, which is determined mainly by the change of the O-H or O-D stretching frequencies when the dimers are formed.

The Pitzer equation for the calculation of the second virial coefficients
of pure compounds, written in its more updated form according to Tsonopoulos (Prausnitz et al.
The second virial coefficients
in deionized water increased with increasing acrylamide content in the copolymers.
