Abstract
NMR diffusion measurements were used to probe the role of water molecules in a resorcinarene capsule in a CDCl3 solution. It was found that the water/resorcinarene ratio affects both the chemical shift and the diffusion coefficient of the water molecules. From the NMR diffusion measurements we could conclude that the major species in the chloroform solution is the hexamer having eight water molecules that are in fast exchange, on the NMR time scale, with the bulk water.Keywords
