Scientific paper

Observations at wavelengths close to 1 mm of 53 Galactic source positions, including most of the available strong CO sources and infrared sources associated with compact H II regions, are described. Strip maps across W49 and W51, and a complete map of Orion, are presented, the latter suggesting a strong correlation between far-infrared radiation from dust and molecular line emission. Spectra of some of the sources are shown. A composite spectrum suggests similar dust cloud properties in the various sources. Comparison of the present fluxes and upper limits with CO excitation temperatures enables the 1-mm optical depths to be estimated.
