Résumé

We present an unbiased spectral survey of a unique massive protostar in the Cygnus-X region: CygX-N63, performed with the 30m IRAM telescope. We identified 48 molecules over 106 GHz of bandwidth. Two prebiotic molecules were found: CH_2NH (methanimine) and NH_2CHO (formamide) and several rare molecules, such as CF^+ (fluoromethylidynium) or PN (phosphorous nitride). The spectral profiles and the population diagrams of the molecules allowed us to identify three emission regions in the protostar: the envelope, the outflow and a hot core-like region.
