摘要:

通过对一些典型超价分子进行计算和分析,得出了超价分子"d轨道参与"(即外层d轨道杂化和d-p π键概念)不尽合理的结论,并提出了能与实验事实相符的解释方法。此外,本文还阐述了计算化学中基组d函数与d轨道的关系:二者并不等价。

关键词: 超价分子, d轨道, 杂化轨道理论, d-p π键, 极化基组

Abstract:

Based on the Gaussian DFT calculations and analysis on hypervalent molecules, we concluded that the theory that outer valence d orbitals undergo hybridization and get involved in the formation of the d-p π bond is not reasonable.We proposed an explanation that can interpret experimental facts.Additionally, we described the relationship between the d orbital and the d function, which are not equal in computational chemistry.

Key words: Hypervalent molecules, d orbital, Hybrid orbital theory, d-p π bond, Polarization basis sets
