Light scattering data analysis via set inversion

International audienceSet-inversion is applied to recent collision-induced scattering data concerning gaseous CF4. It makes it possible to approximate the set of all vectors of independent components of the CF4 dipole-quadrupole and dipole-octopole polarizability tensors. Numerical analysis shows that short range e¤ects must be taken into account in the high frequency range of each dipole-multipole contribution to the CIS isotropic spectrum of CF4. It also demonstrates the agreement between experiment and recent ab initio calculations
