The influence of the resonance effect,the conjugative effect,and the inductive effect on the absorption frequency of the characteristic chemical bonds have been discussed mainly in this paper.

重点讨论了共轭效应、共振效应、诱导效应对功能团吸收频率的影响，并利用吸收频率数据比较有机物的某些性质，如羰基化合物的亲核取代反应，若香烃的亲电取代反应，某些酸的酸性强弱，有机物的异构现象。

The orientation rule of substituting group s in benzene ring is often explained with electronic effect (inductive effect and conjugative effect).

有机化学教材中通常是从电子效应来解释苯环上取代基的定位规律。

The difference of chemical shifts of heterocyclic hydrogen and carbon resonance signals was produced by the inductive, conjugative, magnetic anisotropy, and stereo effects of substituents for different tropane compounds.

取代基的诱导效应、共轭效应、磁各向异性效应和立体效应对莨菪烷化合物杂环上氢核和碳核的化学位移有较大的影响。

Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

化学位移值表示的诱导效应参数表明甲基具有吸电子诱导效应，经校正后的化学位移值表示的共轭效应参数表明甲基具有微弱的给电子共轭效应，甚至其共轭效应有可能正处于给电子和吸电子的临界状态，总之相对于氢原子，甲基具有吸电子效应。
