## Abstract Multinuclear pulsed gradient spin‐echo (PGSE) NMR diffusion and linewidth measurements were used to probe binding and transport in aqueous Na^+^‐15‐crown‐5, Na^+^‐18‐crown‐6, Cs^+^‐15‐crown‐5 and Cs^+^‐18‐crown‐6 systems. Since direct PGSE observation of many alkali cations is precluded
