概要

• 論文の詳細を見る

• The revised substituent shielding parameter has been proposed in ortho and meta ^1H shift for estimating the π-electron charge densities in substituted benzene series, and, also the resonance contribution has been proved to be a dominant factor in determining the meta ^1H shift. The π-electron charge density calculated from simple sum rule of the revised shielding parameter showed passable agreement with those from HMO treatment.
