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.
17O 魔角旋转（MAS）核磁共振已被用于确定ZrW₂O₈中氧交换的性质。已开发出一种高效的同位素标记技术，一维核磁共振和二维交换光谱（EXSY）实验表明，即使在温度远低于α到β有序-无序相变温度时，所有氧位点之间也会发生相互交换。
