D2o reaction
WebMar 20, 1998 · Calculations on simple reactions, such as H + D 2 → HD + D and F + H 2 → HF + H, compete with experiment in their accuracy. Recent advances in theory promise to extend such accurate predictions to more complicated reactions, such as OH + H 2 → H 2 O + H, and even to reactions of molecules on solid surfaces. WebHydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or …
