The pure rotational spectrum of FeN in its X2
i electronic ground state has been observed in the region of 190 - 530 GHz using direct absorption techniques. The spectrum of CrN has been recorded in its X4
- state as well. These nitrides were formed by reacting metal vapor, produced by a Broida-type oven, with either N2 or NH3 under d.c. discharge conditions. For FeN, eight rotational transitions were measured in the
= 5/2 spin orbit component, where no evidence of
-type doubling was observed. For CrN, five rotational transitions were recorded in which all fine structure components were resolved. These data have been analyzed and rotational and certain fine-structure parameters have been determined. Bonding in metal nitride species is also discussed.
