自1919年N·V·sidywick提出配键的概念以来,络合物的化学键理论得到了迅速发展。1929年H·Bethe提出了络合物的晶体场理论(CFT)三十年代初,L·pauling将电子配对法与杂化轨道理论相结合提出了价键理论(VBT),后来,分子轨道理论把络合物的化学键理论推向了一个新阶段。1965年schaffer又提出了角重叠模型(AOM)。这些理论各自从不同的角度解释了络合物的某些性质。本文将通过八面体络合物的量子力学处理,对晶体场理论提出几点评价。
Since the concept of a bond was proposed by NV Sidywick in 1919, the chemical bond theory of complexes has been rapidly developed. In 1930 H Bethe proposed the crystal field theory (CFT) of complexes. In the early 1930s, L. Pauling proposed the valence bond theory (VBT) by combining electron-pair method with hybrid orbital theory. Later, molecular orbital theory The complex chemical bond theory to a new stage. In 1965 schaffer again proposed a corner overlay model (AOM). Each of these theories explains some properties of complexes from different perspectives. In this paper, through the quantum mechanics of octahedral complexes, some comments on the theory of the crystal field are given.
