NaB_n(n=1—9)团簇的几何结构和电子性质
Geometric structure and electronic characteristics of NaB_n(n =1—9) clusters

摘要: 应用密度泛函理论(DFT)中B3LYP方法在6-311+G(d)水平上计算并分忻了NaB_n(n=1—9)团簇的几何结构及电子性质.同时,讨论了团簇的平均结合能、能级间隙、二阶能量差分和极化率.研究表明:NaB_n(n=1—9)团簇基态绝大多数为平面构型.能级间隙和二阶能量差分结果表明NaB_3与NaB_5是幻数团簇.另外,对平均线性极化率和极化率的各向异性不变量研究表明基态NaB_n团簇的电子结构随B原子的增加虽然趋于紧凑,但尚未形成特定的堆积方式.

Abstract: The geometric configurations,electronic structures,vibrational frequencies,and average binding energies of NaB_n(n = 1—9) clusters are studied using the B3LYP DFT method at 6-311+G(d) level.The stabilities of the ground states of NaB_n(n = 1—9) clusters are analysized by means of energy gaps,and secondary energy differences between the ground state structures.And the polarizations are studied. -
