Besides ions of the Me+ type several fragmentary ions (e.g. N+, O+, NO+, MeN+ and MeO+) and also cluster ions Me x O y + (x ≥ 2, 0 ≤y ≤ 2) were detected. Signals of a more molecular type with respect to the reactant gas, e.g. MeNO+, were only found for Co, Ni, Cu, Pd and Pt. From this, one may infer that for the other targets the nitrogen oxides will exist preferentially in a dissociatively adsorbed state at the metal surface. Several aspects of secondary ion emission can be explained assuming a different degree of oxidation for the metals under the influence of reactant gas.
