The ratio between the intensities of the various CO line transitions, with the additional information about the isotope abundance, should enable us to probe the optical depth in the molecular clouds in galaxies. There are, of course, problems in interpretation as a result of the unknown structure of the clouds, their distribution and temperature. These problems become particularly important since most of the present data are derived in the vicinity of nuclei of galaxies.
