Abstract: A numerical procedure for expanding electron repulsion integrals 〈mm|nn〉 on degenerate molecular orbitals of γ symmetry (γ=e, t, g, h) into integral invariants (reduced matrix elements) Hk(γ, γ) is suggested. The latter are analogous in their sense to Slater-Condon parameters Fk(l, l) for atoms with an electronic configuration lN. The method is applicable to nonlinear molecules of arbitrary symmetries, including “not readily reducible” groups.
