✦ Synopsis

The reactions of C,Sc+ (n = 2-6) with O2 have been studied by using an rf ion trap. C&c+ was produced by the laser ablation of a mixed sample of graphite and scandium. Observed reaction product ions were ScO+ for all C,Sc.+, and BcD: only for C.Sc+ with odd n. In the case of C&c+, the loss of 2C neutrals, leading to C&+ production, was alsO observed. The estimated rate constants of C,,Sc+ +Oz reactions were found to alternate in magnitude with the cluster size; C,Sc+ clusters with even n have rate constants much lower than those with odd n.
