Searching for new stable units of transition metal composite clusters by isomer-separation method

本研究采用离子迁移谱法对过渡金属复合簇（ZnO）n+和（CoO）n+的异构体离子进行了分离，并对其结构进行了划分。因此，我们研究了它们的结构转变和退火效应对尺寸的依赖性。我们还研究了碳和硅簇离子的异构体依赖解离和化学反应。我们已经观察到同分异构体依赖的碎片离子分布，并成功地确定了分离的同分异构体离子氧化和氘化的反应速率常数。

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.
