Diffusion Isotope Effects in Isotope Mixtures
Berichte der Bunsengesellschaft für physikalische Chemie, 1972AbstractThe tracer diffusion of deuterium and tritium in the β‐phase of PdHn has been measured by means of special techniques, the time lag method with mass spectrometer or counter tube as detector, and the decay function of isotope exchange. It has been found that D atoms as tracer in β‐PdHn, i.e.

Electrochemical Isotope Effect and Lithium Isotope Separation
Journal of the American Chemical Society, 2009A large electrochemical isotopic effect is observed upon the electrodeposition of lithium from solutions of propylene carbonate producing isotopically light metal deposits. The magnitude of fractionation is controlled by the applied overpotential and is largest close to equilibrium.

Nature, 1954
DURING the past few years, there has been a growing interest in the differences in reaction-rates which arise from isotopic substitution. Attention has been largely focused on the isotopes of carbon, nitrogen and oxygen1, but recently the effect has been demonstrated for heavier atoms, in particular for the isotopes of sulphur2.

Mechanism from Isotope Effects
Isotopes in Environmental and Health Studies, 1998Abstract Isotope effects represent perhaps one of the most versatile tools available to investigators interested in the determination of reaction mechanism, particularly in the case of the mechanistic enzymologist. Interpretation of isotope effect data is somewhat more difficult for enzyme reactions, since the chemical or isotope-dependent step(s) is(

Mass-Independent Isotope Effects
The Journal of Physical Chemistry B, 2013Three fundamental properties of atomic nuclei-mass, spin (and related magnetic moment), and volume-are the source of isotope effects. The mostly deserved and popular, with almost hundred-year history, is the mass-dependent isotope effect. The first mass-independent isotope effect which chemically discriminates isotopes by their nuclear spins and ...
