Abstract
Ab initio SCF calculations in the Hartree-Fock approximation of static parallel and perpendicular polarisabilities and their first derivatives for CO2 and N2 are reported. For N2, results for values of the internuclear separation from 1.7 to 2.4 a0 are presented. For CO2, only the linear symmetric-stretch geometries are considered, and polarisabilities are given for values of the oxygen-carbon separation from 2.0 to 2.4 a0.
