Investigation of S34 in Nature and in the Laboratory

Abstract

The results of a survey on the relative abundance of sulfur isotopes are presented, together with a review of previous work on the same subject. The possible causes of the variations found, and the biological and geological significance of these varia­tions is discussed. In addition, the equilibrium constant for the isotopic exchange between hydrogen sulfide and hydro­sulfide solution is determined experimentally and the results related to theoretical cal­culations based on partition functions.
