Abstract
The basic principles and illustrative applications to enzyme mechanisms of solvent isotope effects, with emphasis on the use of rate measurements in mixtures of protium and deuterium oxides (βproton inventoriesβ), are reviewed over a period slightly shorter than the history of this Journal. The principles in their current formulation are traced to publications of the 1960s and the illustrations are taken from publications that have appeared in 2006β2007.

The decreased kinetic acidity of deuterium relative to hydrogen can be used to gain an advantage in the reductive cyclization of an alkenyllithium species onto a ketone. The intermediate alkenyllithium can add to the carbonyl or abstract an a-proton, giving rise to two products. The yield of the cyc
A study of fluorescence quantum yields and fluorescence lifetimes of the cyclic azoalkanes I and II reveals a striking dependence of @P and rF on solvent and on isotopic substitution (OH 4 OD). A mechanism involving specific deactivation of the fluorescent state from a hydrogen bonded complex is pro
