目前讲述配位场理论的教科书,关于在不同对称性的配位场作用下中心离子d轨道能级分裂式样的推引方法,大致可分为两类。一类是由静电直观模型入手,进行推引,另一类是应用群论方法,进行较严格的推导。这两种方法对我国当前的化学、化工系高年级学生都不大适宜。前者在现行一年级基础无机化学教材中即已采用,后者则因我国目前化学、化工系大学生多未开设群论课而难以施行。为了适应高年级大学生的有关课程的需要,较好地做到承前启后,这里介绍一种应用简单的对称性和点群知识推引配位场能级分裂式样的方法[7]。
At present, the textbook about coordination field theory is introduced. There are two types of methods to deduce the energy level splitting pattern of the central ion d orbit under the action of ligands with different symmetries. One is from the electrostatic model to start, to infer, the other is the application of group theory, the more rigorous deduction. Both of these methods are not suitable for the current senior students in chemistry and chemical engineering in our country. The former has been adopted in the current first-year basic inorganic chemistry textbook, while the latter has been difficult to implement due to the fact that more students in the chemical and chemical engineering departments in our country do not yet have a group course. In order to adapt to the needs of higher grade college students, it is better to make a breakthrough. Here we introduce a simple method of symmetry and point group knowledge to deduce splitting field level energy.
