Abstract
17O magic angle spinning (MAS) NMR has been used to determine the nature of oxygen exchange in ZrW(2)O(8). A highly effective isotopic labelling technique has been developed and 1D NMR and 2D exchange spectroscopy (EXSY) experiments have revealed that mutual exchange occurs between all oxygen sites, even at temperatures considerably below the alpha to beta order-disorder phase transition.Entities:
