Article Abstract:
An attempt is made to investigate the pore size as well as the local structure about the confined xenon atoms, for this high-pressure (super 129)Xe NMR measurements were carried out on dehydrated (plus mn)-[Co(en)3]Cl3. The (super 129)Xe NMR line shape observed at each pressure is characterized by an axially symmetric chemical shift tensor, implying that this compound has a nanopore with cylindrical symmetry.

Article Abstract:
The [.sup.129Xe] NMR line shapes of xenon adsorbed in the nanochannels of the (plusmn)-[Co(en)3]Cl3 ionic crystals were calculated by grand canonical Monte Carlo (GCMC) simulations. The nanochannels of (plusmn)-[Co(en)3]Cl3 provided a simple model system that serves as building block toward understanding xenon chemical shifts in more complex porous materials containing transition metals.

Article Abstract:
The dependence of the local structure and dynamics of heavy water in plusmn -[Co(en)3]Cl3.nD2O on the dehydration process is studied by examining the line shape of (super 1)H MAS NMR spectrum as a function of the water content and temperature. The well-resolved (super 1)H NMR signal for the hydration water is observed by probing the trace of (super 1)H nucleus contained in heavy water.
