Stable Compositions and Structures of Copper Oxide Cluster Cations Cu _n O _m ⁺ (n = 2-8) Studied by Ion Mobility Mass Spectrometry.

ABSTRACT: Stable compositions and structures of copper oxide cluster cations have been studied by ion mobility mass spectrometry (IMMS) and density functional theory calculations. Cluster ions of the series Cu _n O _m ⁺ were predominantly observed with n:m ≈ 2:1 in the mass spectrum. Collision cross sections (CCSs) of the cluster ions with n:m ≈ 2:1, determined by IMMS, were found to increase monotonically with cluster size. In addition, the CCSs of Cu _n O _n ⁺ and Cu _n O _n-1 ⁺ (n = 2-8) were examined, and stepwise increases were observed for Cu _n O _n-1 ⁺ series. These cluster structures were assi
