摘要: 本文提出了在非限制Hartree-Fock方法计算的分子轨道基础上,计算分子价电子体系能谱和多电子状态的不可约张量方法。使用这种方法,计算了具有近似正八面体对称性的过渡金属化合物MnBr64-、MnCl64-、FeCl63-、MnF64-、Mn(H2O)62+、Co(NH3)63+、NiF64-、Ni(H2O)62+、Ni(NH3)62+的d-d跃迁能谱。理论计算结果与实验符合较好,误差为若干k cm-1. |

Abstract: An irreducible tensor method based on unrestricted Hartree-Fock method for calculating many-electron states and energy levels of valence electron system is presented. By means of this method, the electronic structures of following octahedral transition metal complexes have beenstudied: MnBr64-、MnCl64-、FeCl63-、MnF64-、Mn(H2O)62+、Co(NH3)63+、NiF64-、Ni(H2O)62+、Ni(NH3)62+. The calculated excitation energies agree with the observed ones within several kcm-1. |
Keywords: irreducible tensor many-electron state UHF d-d transition octahedral transition metal complex |
