SCF-CI calculations of the potential energy curve and one-electron property curves of theX1 g + ground state of N2

  • William I. Ferguson
Original Investigation


The energy and important one-electron properties of the nitrogen molecule are evaluated in the1 g + ground state for various internuclear separations near the equilibrium geometry, at the SCF-CI level. Both our Roos CI and Graphical Unitary Group (GUG) programs were used in performing single and multiple root CI computations. The one-electron properties included are the quadrupole and hexadecapole moments (both with respect to the centre of mass) and the electric field gradient at the N nucleus. Dependence of the properties upon the vibrational quantum number are evaluated using the Dunham analysis scheme.
