Paper Abstract

Pioneering observations of far infrared lines from astronomical sources gave been made possible in the past few years by NASA's Kuiper Airborne Observatory (KAO). This is primarily because spectroscopy from ground based sites in the wavelength region from about 20 to 350 microns is precluded by telluric water vapor absorption. Lines in this wavelength range characterize all the phases - molecular, neutral atomic, and ionized - of the inter-stellar gas. They provide both unique informatio2 and information complementary to that available from measurements at other wavelengths.
