Isotope effect
Encyclopedia
Isotope effect can refer to:
- Kinetic isotope effectKinetic isotope effectThe kinetic isotope effect is the ratio of reaction rates of two different isotopically labeled molecules in a chemical reaction. It is also called "isotope fractionation," although this term is somewhat broader in meaning...
- Magnetic isotope effectMagnetic Isotope EffectMagnetic isotope effects arise when a chemical reaction involves spin-selective processes, such as the radical pair mechanism. The result is that some isotopes react preferentially, depending on their nuclear spin quantum number I. This is in contrast to more familiar mass-dependent isotope effects....
- Superconductive transition temperature varying by isotope atomic weight; See BCS theory#Successes of the BCS theory
