Isotope fractionation describes fractionation processes that affect the relative abundance of isotopes, phenomena which are taken advantage of in isotope geochemistry and other fields. …

某元素的同位素在物理、化学、生物等反应过程中以不同比例分配于不同物质之中的现象称为同位素分馏（isotopic fractionation）。 平衡态下的矿物或分子之间的同位素分馏，可以用来指示 …

The equations can be used to describe an isotope fractionation process if: (1) material is continuously removed from a mixed system containing molecules of two or more isotopic …

Isotopic fractionation refers to the relative partitioning of heavier and lighter isotopes between two phases in a natural system. It includes equilibrium fractionation, where isotopes exchange …

isotopic fractionation, enrichment of one isotope relative to another in a chemical or physical process. Two isotopes of an element are different in weight but not in gross chemical …

Isotope fractionation is the observed difference between a given compound and another compound (usually derived from it) and may refer to a process or to a whole series of …

!Kinetic isotope fractionation : "One isotope reacts, diffuses, or evaporates faster than the other. "Can be due to chemical, physical, or biological processes. "Usually, the lighter isotope reacts …

At the basis of isotope partitioning is the difference in rate at which two isotopes of the same molecular species will react in a thermodynamic reaction. The result is a disproportionate …

2024年9月11日 · In principle, primary and secondary kinetic isotope effects can be distinguished. A primary fractionation is based on a bond cleavage or formation in which the relevant …

Equilibrium isotope fractionation is the partial separation of isotopes between two or more substances in chemical equilibrium. Equilibrium fractionation is strongest at low temperatures, …
