摘要： 用密度泛函B3LYP方法对PuX＋(X=H，O，N，C)分子离子体系进行了理论研究.结果表 明，这些分子离子的基态电子状态分别是X 7Σ-(PuH＋)、X 6Σ-(PuO＋)、X 5Σ＋(P uN＋)和X 8Σ-(PuC＋)；势能函数为Murrell-Sorbie势函数.并得到了相应的几何性质、 力学性质和光谱数据.

关键词: 分子离子, 结构, 势能函数, 稳定性, 密度泛函理论(DFT)

Abstract: The theoretical study on PuX＋(X=O,H,N,C) using density functional met hod(B3LYP) shows that PuO＋、PuH＋、PuN＋ and PuC＋ can be stable. Ground electr onic states are X 6Σ-(PuO＋)、X 7Σ-(PuH＋)、 X 5Σ＋(PuN＋) and X 8Σ-(PuC＋) respectively,and their potential energy functi ons are in well agreement with the Murrell-Sorbie function,their force constant s and spectroscopic data have been obtained.
