Concurrent Ion—Molecule Reactions. II. Reactions in X—D2 Mixtures

Abstract

The formation of XD⁺ in X—D₂ mixtures where X is CO, A, CO₂, and CH₃CN is shown to be the result of the two concurrent ion—molecule reactions $$\begin{array}{c}{\mathrm{X}}^{+}+{\mathrm{D}}_2\to {\mathrm{XD}}^{+}+\mathrm{D},\\ {\mathrm{D}}_2^{+}+\mathrm{X}\to {\mathrm{XD}}^{+}+\mathrm{D}.\end{array}$$ The cross sections for the individual reactions have been measured and compared to theoretical predictions.
