Scientific paper

We report new 12_CO 1 --> 0 observations of 5 nearby dwarf irregular galaxies with low oxygen abundances. None of the galaxies are detected. Two of these galaxies have not been previously observed in CO, and for the other three we improve upon the existing upper limits. In the case of Leo A, we do not confirm a previous detection. This non-detection is consistent with other non-detections of galaxies with similar metallicities. Combining our new data with data from the literature, we find strong evidence that the CO emission in dwarf galaxies depends upon the metallicity, and evidence that it may depend upon another property as well. Because it is almost never detected in dwarfs with oxygen abundance 12 + log (O/H) <= 8.0, CO is not a good tracer of the molecular content of low metallicty dwarf galaxies.
