Israel, F.P., 1980: CO observations of several galactic H II regions. Astron. J., 85, 1612-1630, doi:10.1086/112840.

Maps of the CO emission at a resolution of 8 arcmin are presented for seven H II regions or H II region groups; the results of a search for CO emission near seven more are also given. CO was detected near all but two of the observed objects. The distribution of ¹²CO and ¹³CO near S142, S157, and S159 was mapped at a resolution of 2.3 arcmin. The S147/S153 group of H II regions is shown to consist of physically related objects; it is a region of active star formation. The results show a complicated molecular cloud structure near most observed H II regions. There is a tendency for decreasing CO cloud mass when H II regions in more evolved stages are observed. The relevance of these results for the understanding of individual H II region/molecular cloud complexes, and for general aspects of the star-formation process, is briefly discussed.
