Spectroscopic properties, ionization potentials, dissociation energies, and the 1A1−3B1 energy separations were determined for SnX2 and PbX2 (X=Cl,Br,I). The methods of calculations employed were complete active space self-consistent field (CASSCF) followed by multireference single+double configuration interaction (MRSDCI). The ground state for all these molecules corresponded to a 1A1 state, followed by a 3B1 state as the first excited, and the 1B1 state as the second excited state. The ground states of positive ions of these species were computed to be the 2A1 state. The 2B1−2A1 energy separations of the positive ions were computed. The 1A1−3B1 energy separations are: 60.0 kcal/mol for SnCl2, 55.5 kcal/mol for SnBr2, 47.1 kcal/mol for SnI2, 69.7 kcal/mol for PbCl2, 65.0 kcal/mol for PbBr2, and 53.8 kcal/mol for PbI2. The properties of the 1A1 ground state are Re=2.363 (Å), θe=98.4°, μe=3.739 (D), I.P.=9.72 (eV), and De=3.50 (eV) for SnCl2; Re=2.535 (Å), θe=99.7°, μe=3.400 (D), I.P.=9.34 (eV), and De=3.22 (eV) for SnBr2; Re=2.738 (Å), θe=100.9°, μe=2.863 (D), I.P.=8.62 (eV), and De=2.52 (eV) for SnI2; Re=2.542 (Å), θe=100.8°, μe=5.289 (D), I.P.=10.02 (eV), and De=3.19 (eV) for PbCl2; Re=2.684 (Å), θe=101.5°, μe=5.038 (D), I.P.=9.64 (eV), and De=3.06 (eV) for PbBr2; and Re=2.878 (Å), θe=103.6°, μe=4.277 (D), I.P.=8.82 (eV), and De=2.51 (eV) for PbI2. The general trends for SnX2 and PbX2 (X=Cl,Br,I) are discussed.
