Abstract

This paper presents a comprehensive theoretical treatment of the low-lying electronic states of the molecular ion AsCl⁺ correlating with the lowest dissociation asymptote As⁺ (³P) + Cl (²P). All-electron CASSCF + CI calculations have been made with averaged atomic natural orbital basis sets. There are four bound states, namely X²Π, A²Π, 1 ⁴Σ^- and 1 ⁴Π. Spectroscopic constants are calculated for the bound states and are in good agreement with experimental data for the doublet states.
