Configuration interaction (CI) calculations restricted to single excitations with respect to a closed-shell ground state determinant have been performed using modified CI-Hamiltonian matrix elements. Shifted molecular-orbital (MO) eigenvalues from Kohn-Sham density functional theory (DVI') are used
