Scientific paper

The J = 4 → 3 transition of HCN at 354 GHz has been detected in the Orion Molecular Cloud using the UK Infrared Telescope with an InSb heterodyne detector. Both the "spike" and "plateau" sources are seen, and the physical parameters of these are derived from a model of the cloud. On certain plausible assumptions, the extended spike source is estimated to have n(HCN)/n(H2) = 8 × 10-10, n(H2) = 4.5 × 105 cm-3 and TK = 100K, while the compact plateau source has n(HCN)/n(H2) = 2 × 10-8, TK = 250K, and n(H2) = 1 × 106 cm-3.
