An ab initio SCF calculation of the polarizability tensor of sulphur dioxide

The principal components of the static electric dipole polarizability have been calculated by an ab initio coupled perturbed Hartree–Fock (CPHF) method. The calculated components are sufficiently accurate so that a choice can be made between the two different sets of experimentally consistent values in favor of the negative anisotropy parameter αxx−ᾱ.
