Calculation of electric dipole hypershieldings at the nuclei in diatomic molecules

The third-rank electric hypershielding at the nuclei of eight diatomic molecules and carbon dioxide has been evaluated at the Hartree-Fock level of accuracy (i) by straightforward use of its definition within the Rayleigh-Schrödinger perturbation theory and (ii) by a pointwise procedure for geometri...
