用密度泛函理论(DFT)的B3LYP方法,在6-311G*水平上对BmN(m=2-9)团簇的几何构型、电子结构、振动频率、自然键轨道(NBo)等性质进行了理论研究.通过对基态结构的异构化能、核独立化学位移(NICS)和能量二次差分的讨论,得到了BmN(m=2-9)团簇结构的稳定性信息.
The geometric configurations, electronic structures, vibrational frequencies, and natural bond orbital (NBO) of BmN (m=2-9) clusters were studied using the B3LYP DFT method at 6-311G* level. The stabilities of the BmN (m=2-9) were analysized by means of energy difference, nucleus independent chemical shifts (NICS), and secondary energy differences of the ground state structures.
