“…Lord Rayleigh himself pointed out [24] that quasi-static dipolar approximations cannot accurately describe densely packed arrays and multipolar approaches have been developed through the years to correct these issues [25]. The noncausal features highlighted in this paper, however, are not directly related to these well-understood effects and limitations.…”

“…(22). The slope of the profile for the mean attractive energy turns out to be fairly constant over the interfacial region At this stage we should point out that the second-order term has to be included in the full free energy functional of the inhomogeneous system in order to recover the SAFT-VR expressions of the homogeneous bulk phase.…”

The SAFT-VR DFT Helmholtz free energy functional developed by Gloor et al., [J. Chem. Phys. 121, 12740 (2004)] is revisited and generalised to treat mixtures. The functional, which is based on the statistical associating fluid theory for attractive potentials of variable range (SAFT-VR) for homogeneous fluids, is constructed by partitioning the free energy density into a reference term (which incorporates all of the short-range interactions and is treated locally) and an attractive perturbation (which incorporates the long-range dispersion interactions). In this work, two different functionals are compared. In the first, one uses a mean-field version of the theory to treat the long-range dispersive interaction, incorporating an approximate treatment of the effect of the correlations on the attractive energy between the segments by introducing a short range attractive contribution in the reference term. In the second, one approximates the correlation function of the molecular segments in the inhomogeneous system with that of a homogeneous system with an average density of the two positions, following the ideas 2

We study Rayleigh-Brillouin scattering in gases of N2, O2, and SF6 molecules, Kr atoms, and He-Xe and He-CO2 mixtures at pressures ranging from 1 to 3 bar and using two different experimental setups. In one setup, we measure spectra of light scattered by thermal density fluctuations (spontaneous Rayleigh-Brillouin scattering); in the second setup density waves are induced in the overlap region of two counterpropagating laser beams (coherent Rayleigh-Brillouin scattering). We compare measured spectra to the Tenti models and to a recent model for mixtures. We find new values of the bulk viscosity, which is a parameter in line-shape models that allows for internal degrees of freedom. Both experiments agree on the value of the bulk viscosity. Our results indicate a need for new line-shape models for mixtures of molecules with internal degrees of freedom.
