用~ 1H-2NMR研究了钾镁矾中氘代水的性质。证据表明，水的变化状态从液体到固体在室温下的水化反应，形成钾镁矾。水中的氘核在氢键晶格中经历快速的四面体跳跃，就像在（H2O）-H-2冰中观察到的那样。
H-2 NMR was used to study the nature of deuterated water in kanemite. Evidence is presented that shows that the water changes state from liquid to solid at room temperature during the hydration reaction that forms kanemite. The deuterium nuclei in the water experience rapid tetrahedral jumps in a hydrogen-bonded lattice like those observed in (H2O)-H-2 ice.
