Theoretical Estimates of Equilibrium Isotope Effects Among Aqueous Sulfur Compounds
Theoretical Estimates of Equilibrium Isotope Effects Among Aqueous Sulfur Compounds
Included here are links to two spreadsheets based on data tables from our publications that can be used to calculate theoretical equilibrium sulfur isotope fractionation factors among a wide variety of aqueous sulfur compounds. The aim of these studies is to provide a set of internally consistent constraints on equilibrium sulfur isotope fractionation factors among most aqueous sulfur species considered relevant to natural systems.
Excel Spreadsheet 1: Eldridge et al. (2016): Sulfide, sulfite, sulfoxylate, thiosulfate, and sulfate species
Excel Spreadsheet 2: Eldridge et al. (2021): Polysulfides, polysulfur radical ions, polythionates, elemental sulfur, sulfide, and sulfate species
