摘要 在相对论有效原子实势 (RECP)近似下 ,用密度泛函 (B3LYP/LANL2DZ)方法 ,优化计算PdYn,Pd2 Yn(n =1~ 4 )团簇的结构、光谱性质和能级分布。结果表明 ,团簇基态的HOMO能级和LUMO能级均为负值 ,团簇易得电子 ,团簇的能隙 (HLG)小 。 The structures,spectroscopic properties and energy levels of PdY_n,Pd_2Y_n(n=1~4) clusters have been optimized by Density Functional Theory (DFT) method with Relativistic Effective Core Potential(RECP) using Gaussian 98 code. The results show that the HOMO and LUMO of the ground states of PdY_n,Pd_2Y_n(n=1~4)clusters are negative. The HLGs of PdY_n,Pd_2Y_n(n=1~4) clusters are narrower, and the chemical activation strengthens.
