Studies of the central parts of nearby galaxies as well as of distant luminous galaxies, made with the IRAM 30 m telescope, show that the CO 2−1/1−0 ratio is 0.6 ± 0.2. Many galaxies in the distant luminous sample are new detections. In contrast to the distant luminous sample, the galaxy NGC 3147, at cz = 2800 km/s, has a more modest infrared luminosity, but a large mass of molecular gas, which is not concentrated in the center of the galaxy.
