Kinetics and Mechanism of the Formation of Water Cluster Ions from O2(Plus) and H2O in He, AR, N2, and O2 at 296 K

摘要

The reaction sequence leading from O2(+) to H3O(+)-H2O was examined in He, Ar, N2 and O2 carrier gases in a flowing afterglow system. The rate constants for the reactions were measured and the kinetic analysis for their determination is presented. For M = N2, two new steps involving the formation and reaction of O2(+)-N2 were proposed and examined. The rate constants are discussed and compared with other experimental values. (Author)
