    The Formation of Molecular Clouds and Massive Stars
    In this talk I consider two questions. First, I investigate the formation of molecular clouds from diffuse interstellar gas. It has been argued that the...

    The importance of improved collision cross sections in deriving interstellar cloud parameters from rotational line spectra
    It is shown how present uncertainties in the ability to compute collisional cross sections for rotational transitions can lead to order of magnitude errors in...

    The M(17)SW molecular source - Internally or externally heated?
    From a measurement of the J = 3 - 2 rotational emission line of hydrogen isocyanide, and a literature value for that J = 1 - 0 line (Snell, 1979), the...
