Abstract
It has been known for some time that the best place to find CO is toward HII regions. Nevertheless, there has been no unbiased survey of CO toward HII regions on even a limited basis. To ameliorate this situation, we have attempted to survey all of the optical HII regions accessible with northern hemisphere millimeter wave radiotelescopes. The initial motivation was to get as many points as possible in order to determine the Galactic rotation curve. We have subsequently found that the information contained in our survey has some inherent interest as has already been shown by Fich, Treffers and Blitz (1982). A catalogue of the results is on press in the Astrophysical Journal Supplement Series (Blitz, Fich and Stark,1981).
