摘要：

Despite the absence of water channels, H/D and H 216O/H 218O exchange experiments show that water molecules diffuse rapidly through the crystal lattice of β‐cyclodextrin · 12H2O (CD). Exchange takes place in minutes and follows first‐order kinetics. This is explained by the structural fluctuations of the β‐CD molecules, which became apparent in crystallographic studies and in computer simulations.
