Millimeter-wave spectrum of the CCO radical
Abstract
The pure rotational spectrum of the CCO radical in the 3Σ- ground electronic state has been observed in the laboratory in the region 45 - 185 GHz. The radical was generated in a 3.5 m long free space absorption cell by a DC glow discharge in carbon suboxide (C3O2). Seven rotational transitions of N = 2<-1 to 8<-7 in each triplet sublevels were precisely measured and the observed frequencies were least-squares analyzed to obtain molecular constants.
