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

[Image: see text] 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. Collisi...

description [Image: see text] 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 assigned by comparison of the CCSs obtained via the IMMS experiment with theoretical orientation-averaged CCSs of optimized structures.
