“…The neglect of all angular correlation, referred to as the S-model by Kielich [41], has been used by several authors in various contexts [10,22,24]. Obviously, the S-model does not give rise to any cross contribution, so it is not useful to yield a realistic estimate of the total correlation function in the case of N~.…”

Molecular dynamic simulations and experimental measurements on Raman bands of fluid N2 at about 150 K and two densities (1.05 and 1.8 times the critical density) are reported. Induced effects are accounted for by the dipole-induced-dipole mechanism at the first order. A satisfactory agreement between time correlation functions and spectral shapes derived from simulation and experiment is obtained. A detailed analysis of the different contributions to the total correlation function is reported, either performing or without performing the projection of the collision induced polarizability onto the orientational variables. The density dependence of static and dynamical properties is discussed together with the role played by the cross and pure collision induced contributions. The approximation of neglecting all orientational correlation is successfully used for the estimate of the pure collision induced terms.
