Research Abstract |
Results of a series of theoretical investigations showed that nuclear field shift effect will not produce anomalous fractionations of sulfur isotopes while various surface reaction may produce anomalous fractionation of sulfur isotopes. On the other hand, kinetic isotope effect during abiotic reactions may not deviate from the mass-dependent relationships predicted on equilibrium isotope exchange reactions.
