Abstract

Photoelectron imaging is employed to examine the monomer and dimer anions of CO₂ and CS₂, either isolated or embedded in clusters. In both cases, photodetachment from the dimer anion is compared to the corresponding monomer. The comparison of CS₂^- and (CS ₂)₂^- images reveals dissimilar bands attributed to detachment from different orbitals/species. Yet the photoelectron angular distributions obtained from the monomer and dimer anion cores of (CO₂)_n^- clusters are surprisingly similar. These findings are reconciled with the qualitatively different electronic-structural properties of (CS₂)₂^- and (CO₂)₂^-.
