LIGHT-SCATTERING DATA-ANALYSIS VIA SET INVERSION

Set inversion is applied to recent collision;induced scattering data c oncerning 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 effects must he taken into account in the high-frequency range of each dipole-multipole contribution to the CIS isotropic spect rum of CF4. It also demonstrates the agreement between experiment and recent ab initio calculations.
