摘要
作为地球最主要的化学组分,水对于所有的生命体都至关重要。水合氟离子团簇广泛存在于大气以及水溶液中,并在许多生物化学反应中扮演重要的角色。确定水合氟离子团簇的基态结构是一个非常具有挑战性的工作。本文采用综合遗传算法[1]结合第一性原理的方法系统地搜索了水合氟离子团簇F-(H_2O)_(1-10)的势能面,并得到了它们的基态结构。我们进而采用高精度的MP2方法和B97-D交换关联泛函结合aug-cc-p VDZ研究了水合氟离子团簇的几何结构、能量和谱学性质,并与实验值做对比~([2,3])。
As a major chemical constituent on the Earth's surface, water is crucial adjective to all life. Fluorine water clusters widely exist in atmosphere or aqueous solution and play a very important role for many chemical and biological reactions. Identifying the energy minima of fluorine water clusters is a challenging problem. We have implemented a comprehensive genetic algorithm(CGA) combined with density functional theory(DFT) to search the low energy structures of fluorine water clusters F-(H_2O)_n with n = 1-10. The geometric structures, energies and spectra of the F-(H_2O)_(1-10) clusters were investigated using DFT along with B97-D exchange-correlation functional as well as high-level ab initio MP2 method. The results were compared with the experimental ones.
