Research Abstract |
In this study, isomer ions of transition metal composite clusters, (ZnO)n+ and (CoO)n+ were separated by using ion mobility spectrometry, and their structures were assigned. We have thus investigated size dependences on their structural transitions and annealing effects. We also have investigated isomer-dependent dissociations and chemical reactions of isomers of carbon and silicon cluster ions. We have observed isomer-dependent fragment ion distributions and have successfully determined reaction rate constants for oxidation and deuterations of separated isomer ions.
