Journal ArticleThe kinetic energy dependence of the reactions of Crn+ (n=1-18) with CO2 are studied in a guided ion beam mass spectrometer. The primary product ions are CrnO+, which then decompose by sequential loss of chromium atoms as the kinetic energy is increased. Simple collision-induced dissociation to form the Crn+-1 product ions is also observed. Large cluster ions, n≥9, form the CrnCO2+ adduct at low kinetic energies
