Ion-atom interchange reactions using isotopic species

Abstract

Isotopically labeled species, D⁺, ¹⁵N⁺, and ¹⁸O⁺, have been used to study ion‐atom interchange reactions at room temperature and, the case of D⁺, at lower temperatures. The use of isotopes permits the investigation of interchange reactions involving otherwise identical atoms. The implications of these measurements for reaction kinetics are discussed.
