This is one of the early spectra obtained with the HIFI instrument on Herschel. This HIFI spectrum of a massive star-forming region reveals the fingerprints of a number of key organic molecules, such as formaldehyde (H2CO), carbon sulphide (CS), the formyl ion (HCO+), the ethynyl radical (C2H), and the methyladyne radical (CH).
