Dual Clumped Isotope (Δ47, Δ48) Values for Calcite Grown at Varying pH and Carbonic Anhydrase Concentrations Constrain Equilibrium and Kinetic Isotope Effects

Abstract This study explores the isotopologues m/z 47 (13C18O16O, denoted Δ47) and m/z 48 (12C18O2, denoted Δ48) in CO2 derived from carbonate minerals, focusing on their temperature dependency, kinetic isotope effects, and distinct reaction pathways. By conducting experiments at four temperatures (...
