| 摘 要： | 原子簇化合物的合成方法,由于条件限制,只有B、C、St等非金属元素与过渡金属袈基化合物等较为成熟．贵金属原子簇的合成则较困难．然而,应用激光等离子体反应,可使周期表内几乎所有元素都生成原子簇,为原子簇的生成与研究提供了一条新途径．该方法生成的原子簇在飞行时间质谱仪上可记录到一系列信号,某些信号呈现区域极大（或被称为‘匈数’吵］．郑兰芬等用纯化的红磷粉分别与金粉、银粉混合,在激光等离子作源飞行时间质谱仪上得到一系列谱图【2］：ig与P作用只得到单核xg与P形成的lgy：iE离子簇．谱图较简单,＊沪X最大可达叱叱…

| Abstract: | Structure of 19 cluster cations for AgPn and AumPn generated by laser plasma reactions have been designed according to chemical bond and calculated using DV-Xamethod of quantum chemistry. The results show that P atoms always tend to form P4fragInnt, then combine with Au atoms. The ability of Au atoms to form cluster is stronger than Ag atorns. It combines with P4 fragment after forming chain or cluster of Au atoms.In many-nuclear system the 5d2, 6s1 hybrid orbitals of Au atoms overlap to foTm cluster skeleton orbitals with each other, there axe a lot of metallic nonbonding orbitals. |
