如果揭示水分子团簇的性质，就能更容易地解释和理解水的异常物理特性。水团簇的实验研究已经报道了高度专业化的设备和/或苛刻的实验条件，并没有确定的性质和形成过程。在目前的工作中，我们使用标准的H-1-NMR作为一个通用的和简便的工具，定量研究在环境条件下的液相中的水团簇。这种方法允许收集关于水簇的形成、长寿命、稳定性和物理性质的数据，作为液相中的立方八聚体。
Unusual physical characteristics of water can be easier explained and understood if properties of water clusters are revealed. Experimental investigation of water clusters has been reported by highly specialized equipment and/or harsh experimental conditions and has not determined the properties and the formation processes. In the current work, we used standard H-1-NMR as a versatile and facile tool to quantitatively investigate water clusters in the liquid phase under ambient conditions. This approach allows collection of data regarding the formation, long lifetime, stability, and physical properties of water clusters, as a cubic octamer in the liquid phase.
