应用密度泛函理论(DFT)中的B3LYP方法在6-311+G(d)水平上计算并分析了B10和NaB10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、自然电荷分布和极化率.研究表明:B10团簇的基态为半平面构型,NaB10团簇的基态是以B10半平面为配位基,并与Na原子构成的配位络合物.能级间隙和平均结合能结果表明增加一个Na原子改变了B原子之间的成键作用.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B10团簇增加一个Na原子后NaB10团簇的电子结构更趋于紧凑.
The geometric configurations, electronic structures, vibrational frequencies, and average bind- ing energies of B10 and NAB10 clusters were studied by using the B3LYP (DFT) method at 6-311+G(d) level. The stabilities of the ground states of I310 and NaBIo clusters were analysized by means of energy gaps, average binding energies and the natural bond orbital (NBO) of the ground state structures. And the polarizations were studied.
