欲了解化学分子中电子分布的情况,目前较完整的理论即是分子轨域理论(Molecular Orbital Theory).通常在大一的普通化学课程内容中会作简单的介绍,其实在高中化学课程中也已具有σ键、π键的概念了,只是不甚完整.而普化内容中仅谈到最简单的双原子分子,当分子变大或其中所含原子数目较多时,分子轨域很快就变得很复杂....

MO法(Molecular Orbital theory)是一种用来预测分子性质的理论模型 它建立在电子结构理论的基础上,根据分子的电子结构来预测分子的性质 在用MO法预测下列双原子分子或离子哪个最稳定时,应当先考虑它们的电子结构 根据MO法,分子或离子的稳定性与其电子结构有很大的关系 C2+:C2+是一个离子,它的结构为...
Density Functional TheorySimplified models (model A: [(PhNCH 2CH 2) 3N]Mo; model B: [(PhNCH 2CH 2) 3N]Mo–N 2) based on triamidoamine complexes were proposed to evaluate the electrostatic/orbital effects of the phenyl rings on complexation and reduction of N 2. The effect of systematic...
Small homonuclear Aum (m ≤ 5) and bimetallic PtAun (n ≤ 4) clusters were studied using density functional theory. Both homonuclear and bimetallic clusters tend to form compact two-dimensional structures. All the low-lying Aum clusters have delocalized highest occupied molecular orbitals (HOMOs)...
