VSEPR

The VSEPR theory is mainly applied to predict the geometries of molecules and ions and it is surprisingly useful, but its rules appear somewhat arbitary and its deduction to the relation between VP and the geometry of the electron pairs is troublesome and hard to justify in a rigorous quantum-mechanical formulation, and it cannot expla.

在分子结构理论中,杂化轨道理论在多原子分子的空间构型被实验确定后,能够根据一定的假设给出合理的解释;价层电子对互斥理论主要用于预测分子或离子的空间构型,但其假设有些生硬、推理不够严密,对VP与电子对空间构型之间关系的推导比较繁琐,不易理解,也不能很好地解释一些多原子分子(如PF5、IF7等分子)中存在键长不等的现象。

On the basis of hybrid orbital theory and valence shell electron pair repulsion (VSEPR) theory that anticipate and judge the configuration of covalent polyatomic molecule or iron(not including complexes),a simple and convenient method to calculate the type of the central atomic hybrid orbital directly is deduced by the valence shell electron pairs.
