摘　　要：晶体场理论的主要缺点是忽略了配位原子的价层电子结构特征,因而不能解释光谱化学序列.在考查光谱化学序列中配体配位原子的半径大小及其价层电子结构特征的基础上,提出了配位原子的价层电子———中心原子d电子互斥模型,用以说明配体在光谱化学序列中的位序.还探讨了该互斥模型与分子轨道理论都可以说明光谱化学序列的原因.The main objection of crystal field theory is that it can not explain spectrochemical order because it ignores the valence shell electronic structural character of the coordination atoms.On the basis of considering the size of considering the size of the coordination atoms and their valence shell electronic structure,we proposed the repulsion model between the valence shell electrons of the coordination atoms and the d electrons of the centre atom to elucidate the places of the ligands in the spectronchemical order.In this paper,we also esamined the reason why both electonic repulsion model and molecular orbital theory can explain spectrochemical order.
