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...
定性分子轨道理论Qualitative Molecular Orbital Theory(2)双原子分子的分子轨道,轨道次级作用和多原子分子QMOT基本思路 好了,继昨天讲了一大堆的理论内容(包括还被 @杨知守 前辈狠狠地制裁一遍 )以后,从今天起,接下来所有的内容将基本上跳出纯理论的框架,而开始进入定性分析的各个环节了。 我们上一节已经讲过了分...
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...
Our quest for a bonding theory leads now to molecular orbital theory (MO theory). This is an extension of the atomic orbital theory we have just learned. If it is "correct" for atoms, we must also be able to apply it to molecules, right= We'll start with an "easy" case. Consider...

In chemical 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 th...

3.2a1能量虽然比1e高,但是由于2a1之间重叠要强的多,使得2a1对应的成键轨道能量下降,比1e对应的反键轨道能量还低(本身反键轨道能量上升就大于成键轨道能量下降了),但由于重叠最大,2a1形成的反键轨道也是能量最高的。 得到上图分子轨道以后,我们就可以开始说结论了。
