The high cosmic abundance of carbon and oxygenimplies that small oxocarbons, in particular mono- and dioxides, may be of astrophysical relevance. Besides the extensively-studied CO, CO2 and C2O molecules as well as cations of the former two, C3O has been also detected in dense molecular clouds, carbon star envelopes and toward protostars. Numerous laboratory IR, microwave, ESR and other spectroscopic studies have been carried out on a variety of these species. Formation mechanisms have been also proposed; however, not much is known about the electronic spectra of the linear, cumulenic series (O)CnO. Mass-selected CnOm+/0 (n=8, m=1,2) species have been investigated by means of direct absorption matrix isolation spectroscopy. Ions were produced from mellitic acid anhydride or other precursors and deposited into 6 K neon matrices. Electronic spectra were measured in the 220-1100 nm spectral range.
