Scientific paper
The article presents methods for determining the dynamic energy dissipation rate in cold galactic gas clouds using observations of infrared spectral line radiation from the associated shocked neutral material. Attention is given to the diagnostic capacity of H2 6.9-micron, (O I) 63.2-micron and (C II) 157.4-micron line emission. A modification of the optical configuration of the Spacelab 2 small helium-cooled infrared telescope is proposed such that the instrument can be converted to a spectroscopic facility for surveying the Galaxy in these emission lines.
