The local structure and dynamics of supercooled water: spectroscopic study

水表现出对许多动力学和热力学性质的反常温度依赖性。这些异常现象可以通过氢键网络的存在来解释。因此，阐明液态水的局部结构和相应的动力学对加深我们对水性质的认识具有重要意义。本文利用水的红外光谱分析了过冷水的局部结构和动力学特性。利用密闭空间的反向胶束（直径1-10微米），我们能够在230 K的温度范围内研究深度过冷水。

Water shows an anomalous temperature dependence of many kinetic and thermodynamic properties. These anomalies have been interpreted by the structurizaton by the presence of hydrogen-bond network. Therefore, it is important to elucidate the local structure and correspondent dynamics of the liquid water to deepen our understanding of the properties of water. In this work, infrared (IR) spectrum of water was used to determine the local structure and dynamics of the supercooled water. Using confined space inreverse micelle (1-10 micron in diameter), we were able to study deeply supercooled water in the temperature range to 230 K.
