N2 - Oxidation processes of chromium cluster cations, Cr2+ and Cr3+, are investigated by kinetics measurements under multiple-collision conditions by using a temperature-controlled ion trap. Both of the reactants commonly generate Cr + and CrO + as final products. However, the major reaction pathway to CrO + presents a sharp contrast; Cr2+ produces it directly by a single O 2 collision, whereas Cr3+ does via an intermediate Cr 2O +. Comparison of the kinetics of the intermediate with that of cold Cr 2O + generated in the cluster source reveals that the intermediate Cr 2O + is thermalized promptly with the buffer gas filling the trap.
