Abstract: The 1H and 13C NMR spectra for a series of X-substituted benzanilide were obtained and analyzed on the basis of dual parameter equation. The three constants in the equation were determined. The relative importance of resonance effect and field effect were calculated. It was found that the linear correlation between the chemical shifts of N-1H、C1、C2、C3、C6 and substituent effect σR、σI was good straight line.

Key words: Substituent effect, X-substituted benzanilide, 1H、13C NMR
