The dehydration of RENaY, where RE --La 3Γ· and Ce 3+, has been studied by the 129Xe n.m.r, technique. The [RE (OH)=] {3-')+ cations migrate from the supercages toward the prisms and sodalite cages when x = 0 for La 3+ and x = 0 or 1 for Ce 3+. The chemical shift bs.RE of the xenon adsorbed by the to
