有机结构波谱中二级结构效应机理的新探索(Ⅱ)——π→p共轭效应和超共轭效应

A New Approach to the Mechanism of Second Structural Effect in the Spectra of Organic Structure (Ⅱ)—π→p Conjugate Effect and Ultra Conjugate Effect

当H原子和形成π键的原子相连时 ,π成键轨道和π 反键轨道与H原子的 2p空轨道相互作用 ,组成新的分子轨道 ,这样的结构称为π→p共轭体系。由π→p共轭作用引起的不饱键一系列性质的变化 。

The reciprocity between the orbits of π bond and π * anti bond and the empty 2p orbit of the atom H build new molecular orbits when atom H connects the π bond atom. Such as structure called π→p conjugate system. The character varieties of unsaturated bond due to π→p conjugate action called π→p conjugate effect.
