We present CO (1-0) and (2-1) observations of 33 galaxies in the Coma/Abell 1367 supercluster made with the IRAM 30 m telescope. In addition, we observed four of the galaxies with the 15 m JCMT, at CO (2-1). The indicative molecular gas mass correlates strongly with the dust mass, and a stronger relationship is seen between the far-infrared and CO surface brightnesses than between the simple luminosities. Comparison of CO (2-1) spectra from IRAM and JCMT allows an estimate of the size of the CO emission region, which varies between 10% and 100% of the size of the optical disk, contrary to earlier estimates that the CO is contained within the optical half-light radius. There is a slight suggestion that starburst galaxies have a lower ratio of brightness temperatures, T_b(2-1)/T_b(1-0), than other galaxies.
