Paper Abstract

Spectroscopic observations in the far infrared for astronomical purposes is the primary subject of this discussion. Such spectra allow the study of many common atoms, ions, and molecules in interstellar clouds. In these clouds, temperatures and densities are often low enough that atoms and molecules exist in their lowest states and do not emit at wavelengths much shorter than the far infrared. Furthermore, many important parts of our universe, such as the center of our own galaxy, are obscured by dust clouds and hence cannot be studied at short wavelengths.
