On the observability of far infrared line emission originating from the interstellar medium.
Abstract
Summary. Recent measurements of interstellar absorption lines in the ultraviolet, originating from energy levels above the ground level, can be used to directly compute the expected infrared line radiation. This is done for the 156 t line of C+ in the directions of Oph and Sco and lines of C0. O and Si+. The computed line strengths are considerable and may be strong enough to be detectable with present techniques. Key words: interstellar medium - infrared line radiation
