摘要: ab initio分子轨道方法(RHF,UHF)和密度泛函(DFT)方法研究了团簇Co2S+,Co3S2+的各种可能的几何构型和电子结构,并计算了相应的较稳定构型的振动光谱,发现Co2S+和Co3S2+团簇最稳定结构均具有Cs对称性.对团簇的成键作用机理进行了理论分析.

关键词: 钴-硫团簇, 几何构型, 电子结构

Abstract: The possible geometrical structures of Co2S+, Co3S2+clusters were optimized using the methods of ab initio Molecular Orbital Unrestricted or Restricted Hartree-Fock (UHF, RHF) and Density Function Theory (DFT). The corresponding most stable geometrical structure for Co2S+and Co3S2+are found to be Cs symmetry respectively. The electronic structures and vibrational spectrum of the most stable geometrical structures of Co2S+, Co3S2+are analyzed by the same method. As the result, the calculation can be used for explaining the mechanism of bond forming for the Cobalt-Sulfur cluster.

Key words: Cobalt-Sulfide cluster, Geometrical structure, Electronic structure
