摘要：

Significant deviations from the "normal" intra-elemental isotope fractionation relationship for sulphur isotopes can be caused by isotope exchange by equilibria involving gaseous S-2 and H2S. The phenomenon applies to other elements and it is caused by differences in the crossover temperature of isotope exchange reactions for the different (at least three) isotopes of an element.
