Carbon-dioxide gas rototranslational scattering has been measured at 294.5 K in the frequency range 10-1000 cm(-1) at 23 amagat. The depolarization ratio of scattered intensities in the frequency range 10-1000 cm(-1) is recorded. The theoretical and experimental spectra in the frequency range 10-470 cm(-1) are compared. The anisotropic double differential cross section for scattered light is calculated theoretically considering first- and second-order dipole-induced dipole, first-order dipole-induced octopole, and first-order dipole-dipole-quadrupole light scattering mechanisms as well as their cross contributions.
