Abstract

We study small titanium oxide-CO2 cluster anions in vacuo to understand the fundamental interactions between TiO x and CO2 in the presence of an excess electron. Infrared spectra of [TiO x(CO2) y]- ( x = 1-3, y > 1) were obtained using photodissociation spectroscopy and assigned through quantum chemistry calculations, identifying the formation of carbonato, oxalato, oxo, η2-(O,O), and carbonyl ligands in the core ions of these clusters, with carbonato ligands being the dominant ligand species.
