Description
The number Ns' of rare earth (RE) ions located in the supercage can be derived from the longitudinal proton n.m.r. relaxation time T1 of water adsorbed in 0.64 RENaY zeolite. This is because about 70% of these RE ions are paramagnetic and thus dominate the proton T1. The results do not agree completely with X-ray diffraction studies, but Ns' is in good agreement with recent results of Lee and Rees. (author)
