Notes:
An experimental and theoretical study is presented on the (4s) 2Σ+g, (3p) 2Σ+u, 2Πu, and (3d) 2Σ+g, 2Πg, 2Δg Rydberg states in O+2. Their spectroscopic properties (T0,ωe,ωexe) have been determined using translational spectroscopy. The Rydberg molecules are formed in collisions of fast O2+2 ions with atomic Cs, K, and Na. The potential energy curves of the Rydberg states have been calculated using a self-consistent field/averaged coupled pair functional (SCF/ACPF) method and agree well with the experimental results. The (3p) 2Σ+u state is strongly perturbed by the lowest valence state of the same symmetry. The Rydberg-valence interactions leading to the predissociative decay are discussed.
