Abstract
Observations of the distribution of the CO-molecule in several prominent late-type galaxies indicate that the central HI depressions may very well be filled in with molecular gas (Young and Scoville 1982; Scoville and Young 1983). One such galaxy is M83 (NGC 5236) and, although the angular resolution of the CO-observations is insufficient to discern details on the scale of a spiral arm, it is known that CO is concentrated in the central regions within a radius of 1′. Furthermore, at a resolution of 50″, the CO profile at the position of the nucleus is as bright in M83 as it is for example in NGC 6946, IC 342 and M51.
