摘要： 利用一种处理低对称络离子吸收谱强场方案,推出d5系C2h点群不可约表示对应的能量矩阵。考虑振动电子偶合及双电子激发,解释了MnCl2·2H2O晶体中Mn2+的复杂吸收谱。确认了Mn2+络离子晶场的C2h对称性。

Abstract: A simple and convenient strong field scheme for treating the absorption spectra of the complex ions with lower symmetry groups is suggested. The complete energy matrices of terms corresponding to the irreducible representations of C2hpoint group for d5system are derived.The complicated electronic absorption spectrum of Mn2+in MnCl2·2H2O is analyzed and explained by means of these matrices and by considering the vibronic coupling and double electron excitation.
