Abstract It is pointed out that CO is the most abundant molecule which can be readily detected at radio wavelengths. The lowest rotational transition at 115 GHz is an acknowledged primary tracer of H2 in giant molecular clouds (GMC). It appears that CO might also be a good indicator of spiral structure. The present investigation provides the first complete calibrated map of CO (J = 1-0) emission for the inner Galaxy. Attention is given to telescopes and calibration, the distribution of integrated emission, longitude-velocity distribution, and radial distribution of CO emissivity. It is found that the distribution of integrated CO emission near b = 0 deg between l = 294 deg and 66 deg shows a general symmetry about l = 0 deg with broad maxima near l = 335 deg and 25 deg which are consistent with a ringlike distribution.
