Vrtilek, J.M., C.A. Gottlieb, W.D. Langer, P. Thaddeus, and R.W. Wilson, 1985: Laboratory and astronomical detection of the deuterated ethynyl radical CCD. Astrophys. J., 296, L35-L38, doi:10.1086/184544.

Two rotational transitions of CCD, N = 1-2 at 144 GHz and 2-3 at 216 GHz, were detected in a laboratory glow discharge through deuterated acetylene and helium, after which one, N = 2-1, was detected toward the rich molecular cloud behind the Orion Nebula. The 144 GHz transition is a well-resolved spin doublet split by 55 MHz, the components of which contain hyperfine structure of the order of 1 MHz, so far only partially resolved. From observations toward two positions in Orion, at and near the Kleinmann-Low nebula, the column density of CCD is determined to be 1.8×1013 cm-2 and the isotopic ratio CCD/CCH = 0.05. CCD was not detected at two positions in TMC-1.
