W. Abstract The near-millimeter and submillimeter wavelength emission-line spectrum of the Orion molecular cloud core has been measured at a resolution of 0.2 GHz with a new Fourier transform spectrometer at the Caltech Submillimeter Observatory. The broadband nature of the measured spectrum provides for a uniformly calibrated overview of the dominant broad-line radiators in the cloud core (excluding those molecules whose lines are obscured by our atmosphere). In total, 182 lines from 17 molecular species have been identified. Of these, CO accounts for the brightest lines, but the shock-enhanced SO2 and SO molecules dominate the subterahertz line flux from the cloud core. In addition, highly excited lines of the "density tracers" CS and HCN are seen throughout the measured bands.
