CO is the second most abundant molecule after H2 and it provides indirect probe for the physics of molecular gas in galaxies, i.e density, temperature, opacity. Observation and analysis of CO gas can also shed some light on the gas kinematics which allows us to study the evolution of galaxies. In this study I present single-dish observations of multiple lines of CO across the disk of face-on flocculent spiral galaxy NGC 0628. CO have been detected in all 20 UV-bright regions targeted in the arms and inter-arms of the galaxy.
