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.

Key words: Molecular ions, Structure, Potential enegy function, Stability, Density functional theory(DFT)
