文将d 轨道之分裂示于图Ⅰ,与许多书之图示Ⅱ不同,其差异仅在于表述了εd 之下降,此相当于正、负离子之间的吸引,是离子化合物之生成使体系能量降低而稳定之价键特征。在晶场谱及其相关性质的研究中,只着眼于d 轨道分裂后之能级间距,所以,对图Ⅰ、图Ⅱ之差异皆未作说明。大家知道,晶场理论对d—d 跃迁能作一定的说明,但根本不能说明荷移谱,这是因为它只描述部份价电子—d 电子,而不是描述全部价电子,因而不能用以说 The disintegration of d orbit is shown in Figure I, which differs from the pictorial representation II of many books in that the only difference is the decrease in εd, which is equivalent to the attraction between the positive and negative ions. The generation of ionic compounds reduces the energy of the system The stability of the price key features. In the study of the crystal field spectrum and its related properties, only the distance between the energy levels after the d orbital splitting has been studied. Therefore, the differences between the graphs I and II are not explained. It is well known that the crystal field theory can give some explanation for the d-d transition, but it can not explain the charge-transfer spectrum at all because it only describes part of the valence electron-d electron instead of all the valence electrons and can not be used Say
