摘要: 利用Gaussian-94从头算程序,选择6-31G*基组对P10原子簇的3种构型P10(C2v)、P10(D5h)与P10(C3v)进行几何全优化。3种构型总能量相对值表明,原子簇P10(C3v)具有热力学稳定性;HOMO与LUMO的能级差表明,原子簇P10(C3v)具有动力学稳定性。相反,原子簇P10(D5h)LUMO的能级值较低,易于得到电子而成为负离子。

关键词: P10原子簇, 电子结构, 几何构型

Abstract: Using Gaussian-94 ab initio program,the three configurations of P10 cluster with C2v, D5h and C3v symmetries are performed with full geometric optimization by choosing 6-31G* basis set.The relative energy values of the three configurations show that cluster P10(C3v) possesses a thermodynamic stability;the energy gaps between HOMOand LUMOshow that cluster P10(C3v)possesses dynamic stability.On the contrary, the LUMO′s energyvalue of cluster P10(D5h) is lower than that of the others.It is easier to obtain electrons to become the negative ion.
