KINETIC ANALYSIS OF CONCURRENT ION-MOLECULE REACTIONS IN MIXTURES OF ARGON AND NITROGEN WITH H2, D2, AND HD UTILIZING ION-EJECTION-ION-CYCLOTRON-RESONANCE TECHNIQUES

A technique is developed for using the ion-ejection mode of ion-cyclotron-resonance spectroscopy for determining quantitative ion-molecule rate constants in concurrent reaction systems. Rate constants for the reaction of H2+, D2+,HD+,H 3+, and D3+ with Ar and N 2 are reported along with the concurrent reactions of Ar+ and N2+ with H2, D2, and HD. The results are discussed and compared with the Gioumousis and Stevenson theory and other experimental data where available. The energy dependence of the various reactions are reported as determined by double-resonance experiments. The results are discussed in terms of the phase-space theory of Light. Indications of the mechanism of reaction (complex formation or stripping) were made where appropriate and compared with the crossed-beam data.
