Title: Multinuclear NMR study of the pressure dependence for carbonate exchange in the [UO2(CO3)3]4- (aq) ion

Abstract

Rates of carbonate exchange by two pH-sensitive pathways between aqueous carbonate ion and UO₂(CO₃)₃⁴⁻(aq) are measured by high-pressure NMR. To accomplish this, a custom pulse sequence is employed to achieve selective inversion. Rates of chemical exchange are determined by modeling the return to equilibrium.
