利用Gaussian-92程序在6-31G~*基组下优化P(12)(D_(3d)构型,研究了3P_4(Td)→P_(12)(D_(3d)的相对能量,计算结果为△E=E_((P_(12)(D3d)-3E_(P_4(T_d)=-79.844kJ/mol,优化P_(12)(D_(3d))获得的P-P键键长接近于实验测得的P-P单键键长,并进一步在该基组下计算了P_(12)(D_(3d)原子簇的振动频率,得到的全部为正频率,表明原子簇P_(12)的D_(3d)构型是位能面上的稳定点.
The relative energy of 3P_4 (Td) → P_ (12) (D_ (3d)) was optimized by Gaussian-92 program under the 6-31G ~ * basis set. The calculated results were The bond length of P-P bond obtained by △ E = E _ (P_ (12) (D3d) -3E_ (P_4 (T_d) = -79.844kJ / mol and P_ (12) The measured P-P single bond length, and further calculated the vibration frequency of the cluster of P_ (12) (D_ (3d)) under the basis set, all the positive frequencies obtained indicate that The D_ (3d) configuration is a stable point on the energy plane.
