Photodissociation and Infrared Spectroscopy of U⁺(CO₂)_<i>n</i>, UO⁺(CO₂)_<i>n</i>, and UO²⁺(CO₂)_<i>n</i> Cation-Molecular Complexes.

ABSTRACT: Laser vaporization of uranium in a pulsed supersonic expansion of carbon dioxide is used to produce complexes of the form U⁺(CO₂)_n, UO⁺(CO₂)_n, and UO²⁺(CO₂)_n. These ions are selected in a reflectron time-of-flight mass spectrometer and studied with visible laser photodissociation and tunable infrared laser photodissociation spectroscopy in the region of the CO₂ antisymmetric stretch. The dissociation patterns and spectroscopy of these ions indicate that CO₂ ligands are intact molecules. Although reaction products that form oxide-carbonyl or oxalate species are predicted to be stable, there is no direct evidence in the frequency range studied for the
