| 摘 要： | 采用密度泛函理论B3LYP／6—311＋＋g^＊＊方法对NH3（H2O）n]^-（n=2—4）团簇的结构和频率进行研究，从而得到NH3（H2O）n]（n=2—4）团簇的基态结构，得到的结构与SubhaPratihar等的研究一致．同时，文章还研究了水氨团簇的电子束缚方式和偶极矩，结果表明，在n=2时，电子束缚方式为表面束缚，而在n=3，4时，既有表面束缚方式，又有内部束缚方式．

| Abstract: | B3LYP/6 311＋＋g^＊＊ density funtional theory calculation has been carried out on structure and frequency of NH3（H2O）n]^- （n=2--4） cluster, ground state structures of NH3（H2O）n]^- （n=2--4） clusters were found. The geometries are in agreement with studies by Subha Pratihar. The excess electron binding states and dipole moment were also studied. It is found that only surface binding state for n= 2. However, for n= 3 and 4, both surface and interiorlike binding states are found to exist for the excess electron. |
