Complete-active-space SCF and multi-reference configuration interaction calculations employing large Gaussian basis sets of the general contraction type have been carried out to determine the equilibrium structures and relative stabilities of the ground electronic state R 'I& of the acetylene cation
The energies of the states below 40000 cm-' have been calculated at the CASPTZ( 3, 8)/ANO level. The symmetry assignments and energies at this level are: 2AI 15798 cm-', 2B2 21791 cm-', 4B, 27528 cm-', 2A, 40304 cm-', 2BI 41596 cm-', and 4A2 46879 cm-'. We expect these energies to be within 1500 cm-
## Abstract Using the complete active space selfβconsistent field method with a large atomic natural orbital basis set, 10, 13, and 9 electronic states of the OClO radical, OClO^+^ cation, and OClO^β^ anion were calculated, respectively. Taking the further correlation effects into account, the seco
