Light scattering from gaseous nitrous oxide: Effects of correlation between molecular and intermolecular axes upon the depolarization ratio in terms of the anisotropic potential choice

The Rayleigh depolarized ratio of light scattered from gaseous nitrous oxide has been measured at pressure up to 50 bar and 293 K with a 30 mW He-Ne laser (632.8 nm). The molecular specific scattering of this polar gas (including the effects of the orientational pair correlations (OPC), the collision induced scattering (CIS), and their interferences) are estimated in the DID approximation, assuming a Stockmayer intermolecular potential. We stress the importance of the conditions of symmetry.
