High-resolution slice selection NMR for the measurement of CO_2 diffusion under non-equilibrium conditions

Abstract

We present a simple and an efficient approach using spatially selective NMR to investigate solvation and diffusion of CO_2 in ionic liquids. The techniques demonstrated here are shown as novel and effective means of studying solvated gas dynamics under nonequilibrium conditions without the need for conventional high power gradients.
