Laser-ablated iron, cobalt, and nickel atoms, cations, and electrons have been reacted with NO molecules during condensation in excess neon and argon. The end-on bonded Fe(NO){sub 1-3}, Co(NO){sub 1-3}, and Ni(NO){sub 1-2} nitrosyls and side-bonded Fe-({eta}{sup 2}-NO), Co-({eta}{sup 2}-NO), and Ni-({eta}{sup 2}-NO) species are formed during sample deposition or on annealing. The FeNO{sup +}, CoNO{sup +}, and NiNO{sup +} mononitrosyl cations are also produced via metal cation reactions with NO. Evidence is also presented for the Ni(NO){sub 1,2}{sup {minus}} and Co(NO){sub 1,2}{sup {minus}} anions. The product absorptions are identified by isotopic substitution ({sup 15}N{sup 16}O, {sup 15}N{sup 18}O, and mixtures), electron trapping with added CCl{sub 4}, and density functional calculations of isotopic frequencies. This work provides the first vibrational spectroscopic characterization of Fe, Co, and Ni nitrosyl cations and anions.
