水分子簇结构改变的分子动力学
Molecular Dynamics Studies on Structural Changes of Water Clusters
【摘要】 为揭示水分子团簇形成的理论,在制备具有生物功能的六环结构水的工作基础上,应用量子力学的理论方法,对单个水分子转动惯量进行模拟计算.结果表明,当水分子的键长、键角和偶极矩发生变化时,其转动能谱也随之变化.用分子动力学方法分析了水分子簇微观结构改变后的六环水中原子运动方式,从理论上证明了六环结构水具有稳定存在的动力学特征.
【Abstract】 For proving the theory of formation of water cluster, the moment of inertia of a single water molecular was calculated through the method of quantum mechanics, and the molecular dynamics simulation of structure characteristic of water clusters was carried out on the base of preparation of hexcirclic water which has biological functions. Results showed that with the variation of bound length, bound angle and dipole moment of water mo-lecule, the rotational energy spectrum of water molecule has changed. The hexcirclic structure water formed by water molecule with microstructural change has dynamics stabilization.
