Experimental binary isotropic and anisotropic Stokes spectra of the collision-induced light scattered by gaseous sulfur hexafluoride are measured at the frequency region of the nu(1) vibrational Raman line. They are compared to theoretical intensities due to dipole-multipole interactions. Taking into account the results of a previous study on the interaction-induced intensities in the Rayleigh wings of gaseous sulfur hexafluoride, an experimental value of the derivative of the dipole-octopole polarizability associated with the nu(1) vibrational mode is provided and compared to the result of a recent ab initio calculation.
