Kinetic isotope effects (KIEs) refer to the change in reaction rate caused by the substitution of an atom in the reactants with one of its isotopes, often providing insights into reaction mechanisms. KIEs are particularly significant in reactions involving hydrogen and its isotopes, as the differences in mass lead to measurable changes in bond vibrational frequencies and thus reaction kinetics.

Reaction kinetics is the study of the rates at which chemical processes occur and the factors that influence these rates. It provides insights into the mechanisms of reactions, allowing for the prediction and control of reaction behavior in various conditions.
