Scientific paper

Astronomical observations in the 0.3 to 5 millimeter waveband make possible the detection of spectral lines arising from rotational transitions of interstellar molecules. Dense clouds of molecular gas have been revealed and it is now possible to identify interstellar molecular species and to calculate their relative abundances. Information about the velocity and temperature of the interstellar gas can also be obtained. The implications of the information, revealed by millimeter and sub-millimeter astronomy, for the study of galactic structure and the understanding of star formation are discussed.
