Scientific paper

A search has been made for (C-12)O (J = 1-0) emission in six galaxies two of these (NGC 6814 and NGC 7793) were detected at high resolution. NGC 6414 shows a symmetric, double-peaked spectrum, in which the signature of at least one large CO complex can be distinguished. The spectrum of NGC 7793 is asymmetric, with a stronger blue-shifted side; this is a consequence of the asymmetric distribution of H II regions in the central region of this galaxy. The nondetections are probably mostly due to the limited velocity coverage.
