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...
orbital approximationOur 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 "...
LCAO——MO原理告诉我们,分子轨道MO可以写成AO的线性组合,即:Ψ(MO)=C1Ψ1+C2Ψ2+C3Ψ3+……+CnΨn(其中等式右边的Ψ都是原子轨道波函数)。由于是线性组合,所以n个AO组合就要产生n个MO。 讲完了这些,我们就可以讨论分子轨道理论了。 首先,其基本思想——整体讨论已经提到过了,我们就不多讲述了。 直奔主题...

extend the theory of multigap topology from static to non-equilibrium systems. They identify Floquet-induced non-Abelian braiding, resulting in a phase characterized by anomalous Euler class, a multi-gap topological invariant. They also find a gapped anomalous Dirac string phase. Both phases have ...
