Silica-enhanced NMR diffusometry can distinguish the signals of diastereoisomeric mixtures of supramolecular ion pairs. The experiment has a shorter timescale than Liquid Chromatography, thus allowing an easier characterization of species that are even configurationally labile on the minutes timescale.
