Isotope effect

Isotope effect may refer to:


 * Equilibrium isotope effect, see Equilibrium constant
 * Isotopic shift, effect of isotopic substitution on spectroscopy
 * Kinetic isotope effect, effect of isotopic substitution on chemical reaction rates
 * Magnetic isotope effect, when a chemical reaction involves spin-selective processes, such as the radical pair mechanism
 * Superconductive transition temperature varying by isotope atomic weight: see BCS theory
