Comet Halley’s Gas Composition and Extended Sources: Results from the Neutral Mass Spectrometer on Gndance of more than 10 parent species. The instrument discovered strong extended H.CO and CO sources in the coma of Comet Halley. Polymerized H.CO associated with the cometary dust and evaporating slowly as the monomer is most likely the extended H.CO source. Photodissociation of the H.CO into CO fully accounts for the extended CO source.

Considerable progress has been made recently using radio and infrared spectroscopy, especially with the observations of the two exceptional comets C/1996 B2 (Hyakutake) and C/1995 01 (Hale-Bopp).) 24 molecules likely to be parent molecules outga

Chemical reactions may occur between coma species. Consequently, although chances that an abundant coma species has not been detected are now small, the coma composition is certainly
