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 ...
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...
首先,两个CH3的1a1显然可以组合,形成一个σ成键轨道和一个σ反键轨道(你可以记成1σg和1σu,因为这里取的乙烷是D3d构象的交叉式乙烷,存在对称中心)。 然后,每个CH3基的1e可以组合,形成简并的π成键轨道和π反键轨道(根据中心对称性,你可以记作1πu和1πg),而每个CH3基的2a1也可以形成成键轨道和反键轨道...

4.9.4 Frontier Molecular Orbital Theory It was only through the application of frontier molecular orbital (FMO) theory that a coherent picture of a mechanism based on a concerted nonsynchronous process emerged.19,20 This theoretical solution to the mechanistic dilemma went far beyond the usua...
