应用双层点电荷配位场(DSCPCF)模型和不可约张量方法,系统地推导了D_2对称场中f~N(N=1—13)组态各支谱项~(2S+1)L_J(J=0—8和J=1/2—15/2)的配位场微扰矩阵元,讨论了二角场(D_2,G_(2v))中不同配位数(5—12)的DSCPCF参数A_m~k的具体表达式及其在较高对称场(D_4,C_(4v),D_(2d),D_(4d),D_(2h),D_(4h)和O_h)中的约化行为,建立了相应的数学模型,计算程序DSF.D适用于二角、四角及其立方对称场任意配位数的稀土配合物的光谱解析。
The DSCPCF model and the irreducible tensor method are used to systematically deduce the (2 + 1) L_J (J = 0-8 and J = 1 / 2-15 / 2), we discuss the existence of different coordination numbers (5-12) in the D_2 and G_ (2v) The specific expressions of the DSCPCF parameters A_m ~k and their reductions in higher symmetry fields (D_4, C_ (4v), D_ (2d), D_ (4d), D_ (2h), D_ (4h) and O_h) The corresponding mathematical model has been established. The calculation program DSF.D is suitable for the spectral analysis of rare earth complexes with arbitrary coordination numbers in the angles of the corners, corners and their cubes.
