Isotope Effect and Isotope Separation: A Chemist's View.
Journal of Nuclear Science and Technology, 2002What causes the isotope effects (IE)? This presentation will be centered around the equilibrium isotope effects due to the differences in the nuclear masses. The occurrence of the equilibrium constant, K, of isotope exchange reactions which differ from the values predicted by the classical theory of statistical mechanics, Kcl , is explored.

The electron spin selectivity of radical reactions is accompanied by nuclear spin selectivity, i.e., sorting of the isotopic nuclei relative to their magnetic moment. This property of spin-selective reactions produces separation of magnetic and nonmagnetic isotopes known as the magnetic isotope effect.

This chapter considers hydrogen isotope effects upon rates of proton transfer for reactions in solution not involving solvent isotope effects. Practically speaking, examples are confined to proton transfer to or from carbon, and the point of view most commonly apparent in experimental investigations is that of an organic chemist interested in ...

The substitution of D for H is an elegant probe to use in the elucidation of chemical dynamics, and in particular the solvent isotope effect is a powerful technique for investigating the role of the solvent. This will be the main theme of this chapter. When H2O is replaced by D2O it is inevitable that we are dealing with the effects of substitution at ...
