The sensitivity of the molecule to a broad range of excitations and the ease with which it can be observed in a number of regions has made ammonia one of the most important molecules for studies of molecular clouds.
Osjetljivost molekule amonijaka na širok spektar pobuđivanja i lakoća s kojom se može promatrati u mnogobrojnim područjima učinila je amonijak jednom od najvažnijih molekula pri proučavanju molekularnih oblaka.
