Theoretical and Experimental Fractionation Between Species with Different Oxidation States

Abstract

After it had become clear that equilibrium fractionation between chemical phases containing different hydrogen isotopes could be both theoretically and experimentally determined with perfect agreement (Urey and Rittenberg in J Chem Phys 1:137–143, 1933; Rittenberg and Urey in J Amer Chem Soc 56:1885–1889, 1934; Rittenberg et al. in J Chem Phys 2:48–49, 1934) interest in the equilibria between isotopes of the other light elements also grew.
