On the Second Virial Coefficient [PDF]
The Physics of Fluids, 1959 The second virial coefficient is calculated by a new method which exploits certain results known from formal scattering theory. In particular it is shown that the essential quantity may be expressed as the determinant of the S matrix at a given energy ...

Exact ODE Framework for Classical and Quantum Corrections for the Lennard-Jones Second Virial Coefficient [PDF]
EntropyThe second virial coefficient (SVC) of the Lennard-Jones fluid is a cornerstone of molecular theory, yet its calculation has traditionally relied on the complex integration of the pair potential. This work introduces a fundamentally different approach by

On the Calculation of the Virial Coefficients and Low-Pressure Joule-Thomson Effect for Refrigerant Fluids Using Two Equation of State Models [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 In this study, we calculate virial coefficients and the Joule-Thomson effect at low pressure for refrigerant fluids in order to evaluate the performance of two models of Equations of State (EOS). The studied refrigerants are R123, R124, R143a, and R152a.

Bayesian analysis of static light scattering data for globular proteins.
PLoS ONE, 2021 Static light scattering is a popular physical chemistry technique that enables calculation of physical attributes such as the radius of gyration and the second virial coefficient for a macromolecule (e.g., a polymer or a protein) in solution.

Evidence of Many-Body Interactions in the Virial Coefficients of Polyelectrolyte Gels
Gels, 2022 Simulation studies of aqueous polymer solutions, and heuristic arguments by De Gennes for aqueous polyethylene oxide polymer solutions, have suggested that many-body interactions can give rise to the ‘anomalous’ situation in which the second osmotic ...
