Summary

Pulsed field gradient (PFG) nuclear magnetic resosance (NMR) methods are used to measure translational motions of acetone confined in partially sintered alumina. Relative displacement profiles are obtained at various diffusion times. The preliminary results show the presence of a wide range of pore sizes. The evolution of the profiles with the diffusion time seems to indicate a pore characteristic dimension of 14 m̈m.
