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。
