Abstract

Self-diffusion of water contained in a porous glass is observed to be strongly enhanced if the pore space is only partially filled. This can be explained by a novel mechanism involving indirect molecular exchange between the liquid and the vapor phase. A theoretical model fits the pulsed-field-gradient NMR diffusion measurements with no adjustable parameters. NMR relaxation measurements were performed to provide a characterization of the homogeneity of the samples.
