摘要
用密度泛函B3LYP方法对PuX2+(X=O,H,N,C)分子离子进行了理论研究,结果表明:PuO2+,PuH2+,PuN2+和PuC2+分子离子能稳定存在,基态电子状态是X5∑-(PuO2+),X8∑-(PuH2+),X4∑+(PuN2+)和X9∑-(PuC2+),势能函数为Murrell-Sorbie势函数,并导出了相应的几何性质,力学性质和光谱数据.
The results of the theoretical study on PuX2+ (X = O, H, N, C) using density functional method (B3LYP) show that PuO2+ PuH2+, PuN2+ and PuC2+ can be stable. Ground electronic states are X(5)Sigma (-)(PuO2+), X(8)Sigma (-) (PuH2+) X(4)Sigma (+) (PuN2+) and X(9)Sigma (-) (PuC2+), and their potential energy functions are in good agreement with the Murrell - Sorbie function, and their force constants and spectroscopic data have been worked out.
