title: Dicarbonyls of Carbon and Methylidyne Cations.
abstract: The carbon suboxide cation C3O2+and the protonated carbon suboxide HC3O2+/DC3O2+were produced in the gas phase. The vibrational spectra were measured via infrared photodissociation spectroscopy of their argon- or CO-tagged complexes. Spectroscopic evidence combined with state-of-the-art quantum chemical calculations indicate that both cations have a bent C2vsymmetry and can be designated as dicarbonyls of a carbon cation and methylidyne cation, respectively.
