1 1 Molecular Orbital Theory (MO Theory) 2 MO theory are derived from a linear combination of atomic orbitals of nearby atoms to form the molecular orbitals. – There are two possible combinations • Adding two atomic orbitals forms a bonding MO. • Subtracting two atomic orbitals forms an...
定性分子轨道理论Qualitative Molecular orbital theory(5)定性huckel法和生成轨道法 其实今天本来是要讲超价化合物体系的,但是想起来一方面要在上一节基团轨道应用的基础上做延伸,不能跳的太快,而且今天的生成轨道法也是下一节讲述配合物时的必备方法。 这一节篇幅不会很多,重点是掌握这两个办法的基本思想。 首先我...
Valence Bond Theory (VBT) and Molecular Orbital (MO) Theory were initial techniques for explaining what for chemists was of critical importance, that is, the nature of the chemical bond in molecules. Each approach is still useful today. Molecular Orbital Theory, however, has enjoyed wider ...

作为结构化学的研究者,但凡是学过初等无机化学和有机化学的人,应该都很清楚分子轨道理论了。相信很多人一想到分子轨道理论就会想到十分复杂的计算和各种计算方法,计算软件(我不是学计算化学的,不班门弄斧了(๑> <๑)),但是除了分析个双原子分子,鲜少有人知道如何从定性分析的角度推导复杂分子的分子轨道,即使知...

Inchemical bonding: Molecular orbital theory The alternative quantum mechanical theory of the electronic structures of molecules is MO theory. This approach was introduced about the same time as VB theory but has proved more amenable to quantitative implementation on computers. It is now virtually the...

To review the basics of MO theory, first consider the diatomic molecule F2(full MO diagram inFigure 1). A fluorine atom has 4 valence atomic orbitals: 2s, 2px, 2py, and 2pz. The 2sorbital is lower in energy than the 2patomic orbitals, which all have the same energy. A linear combin...
