Electric polarizabilities and hyperpolarizabilities for the ground state of the nitrogen molecule

Abstract
The static polarizabilities of the ground state of N2 were calculated at three different internuclear separations in the LCAO-SCF-MO approximation. All independent components of electric polarizability tensors up to the fourth rank were included. The isotropy and anisotropy of the γ tensor are γ = 766, Δ1γ = 2264 and Δ2γ = -76e 4 a 4 0 E -3 h respectively (at the experimental internuclear separation of 2·0744 a 0).
