    • The second-order CI method is defined as a multireference CI consisting of single and double excitations from the MCSCF reference functions, in this case into external orbitals chosen to be eigenvectors of the standard MCSCF Fock operator. Only the lowest external orbitals were employed in order that the size of CI matrices is kept practical in our computer systems. Although all external orbitals were used for La, Hf, and Ta atoms, the number of external orbitals used was 20 for Re and Os, 15 for Ir and Pt, and 11 for Au and Hg.

    • The energy threshold depends strongly upon atoms in order to keep the size of the spin-orbit matrices practical: La = 0.11, Hf = 0.13, Ta = 0.12, W = 0.13, Re = 0.16, Os = 0.13, Ir = 0.21, Pt = 0.26, Au = 0.41, and Hg = 0.72 Hartree in the ECP calculations.

    • 2 by 2.43 eV, but relativistic effects reverse the energetic order, to a gap of 0.09 eV. This splitting is re-estimated to be 0.16 eV by AREP (see ref 49b) and 0.27 eV by RECP (see ref 49c). The uSBKJC(f,p) gives 0.47 eV when the MCSCF orbitals are optimized with equal weights for both configurations. The uMINI(3p) provides a gap of -1.53 eV without RESC and of 0.54 eV with RESC.
