综述了无机表面水分子力学和动力学的最新进展。羟基化表面和水-羟基加合物的结构，由LEED-俄歇研究和红外光谱测定，描述了一个细节，最近才解决。新的机械概念的成核和冻结已经从时间相关函数的分析，显示低频角扰动占主导地位的不同行为的水在体相和表面。虽然水分子在液相中的旋转运动可以被解释为通过与邻居建立和破坏氢键而调制的旋转，但吸附在成核催化剂上的水在旋转周期的一小部分中经历不可逆和完全的重新取向。
Recent advances in molecular mechanics and dynamics of water on inorganic surfaces are reviewed. The structures of hydroxylated surfaces and water-hydroxyl adducts, determined by LEED-Auger studies and infrared spectroscopy, are described to a detail only recently resolved. New mechanistic concepts of nucleation and freezing have ensued from the analysis of time-correlation functions, showing that low-frequency angular perturbations dominate the different behavior of water in bulk phases and at surfaces. While the rotational motion of water molecules in the liquid phase can be interpreted as rotation modulated by making and breaking hydrogen bonds with the neighbors, water adsorbed on nucleating catalysis undergoes an irreversible and complete reorientation in a fraction of the rotational period.
