Reactions of laser-ablated niobium and tantalum atoms with NO. Infrared spectra of the NMO, M(eta(1)-NO)(x) (x = 2, 3), and (N-2)(MO2) molecules in solid argon
Laser-ablated Nb and Ta atoms react with NO to give primarily the NNbO and NTaO insertion products, which are identified from isotopic substitution and density functional calculations of isotopic frequencies. Although the mononitrosyls are not observed, annealing gives dinitrosyls the trinitrosyls for both metals. Photolysis markedly increases (N-2)(NbO2) and (N-2)(TaO2), which are stable end products for these reactions.
