Higher order multipolar polarizabilities of carbon tetrafluoride from isotropic and anisotropic light scattering experiments

The higher order dipole-quadrupole and dipole-octopole polarizabilities of carbon tetrafluoride has been determined from isotropic and anisotropic collision-induced light scattering (CILS) experiments of CF ₄ and from anisotropic light scattering of its mixture with argon gas. The CILS spectra are analyzed by using the new updated and different intermolecular potentials. Our final estimates for these properties are ∣ A∣ = (1.051 ± 0.073) Å ⁴ and ∣ E∣ = (1.235 ± 0.282) Å ⁵ which are in excellent agreement with the ab initio theoretical values.
