High field diffusion and exchange NMR were used in combination with kinetic Monte Carlo simulations to study diffusion in a mixture of an amine-functionalized ionic liquid and carbon dioxide. It was found that carbon dioxide exhibits a time-dependent effective diffusivity on a millisecond time scale due to a chemical exchange between the reacted and unrelated states. The details of this type of transport will be discussed in detail.
