Proton deshielding by spatial proximity: An experimental and theoretical study for ortho‐substituted anisoles
A quantitative estimation of the proton deshielding effect produced by a sterically crowded environment was obtained experimentally, based on departures from the chemical shift additivity rule of protons ortho to OCH3 and NO2 groups in benzene derivatives, where a conformational change from these si...
