Abstract
The effects of para-substituents (NO2, CH3, F, OH, NH2) on the barrier to inversion and the geometry at the nitrogen atom in aniline have been studied using ab initio molecular orbital theory; substituents which are π-electron acceptors lower the barrier and lead to a slight flattening of the nitrogen pyramid while π-electron donors raise the barrier and increase the pyramidalization of the bonds at the nitrogen atom.Keywords
