Abstract (from CDS):

We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4-1702.8GHz (band 6b) and 1788.4-1906.8GHz (band 7b) obtained using the HIFI instrument on board the Herschel Space Observatory. We characterize the main emission lines found in the spectrum, which primarily arise from a range of components associated with Orion KL including the hot core, but also see widespread emission from components associated with molecular outflows traced by H₂O, SO₂, and OH. We find that the density of observed emission lines is significantly diminished in these bands compared to lower frequency Herschel/HIFI bands.
