Abstract: We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (
band 6b) and 1788.4 - 1906.8 GHz (
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... ▽ More We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (
