[structure: see text] NMR diffusion measurements were used to probe the role of water molecules in a resorcinarene capsule in a CDCl(3) 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.
[结构：见正文] 利用核磁共振扩散测量来探究水分子在CDCl₃溶液中对间苯二酚芳烃胶囊的作用。发现水/间苯二酚芳烃的比例会影响水分子的化学位移和扩散系数。从核磁共振扩散测量结果我们可以得出结论，氯仿溶液中的主要物种是具有八个水分子的六聚体，这些水分子在核磁共振时间尺度上与大量水快速交换。
