Abstract
The reactions of Ar+ and N2+ with SO2, which have similar energetics due to the nearly equal ionization potentials of Ar and N2, have been studied in a flow–drift tube from 0.04 to 3 eV relative kinetic energy. The energy dependences and product branching ratios of the two reactions are found to be almost identical. With increasing relative kinetic energy, the rate constants show a rather steep initial decline, followed by an equally steep increase. At the lower energies, both reactions yield only the charge‐transfer product SO2+, and at the higher energies, both reactions yield predominately the dissociative charge‐transfer product SO+.Keywords
