Additivity relation for the proton-proton coupling constants of trisubstituted benzenes
Journal of Molecular Structure, 1972Abstract The NMR proton spectra of 12 trisubstituted benzenes in different solvents have been accurately analyzed. The proton-proton coupling constants are calculated by using an additivity relation from the data for benzene and the monosubstituted benzenes.

The effect of substituents on geminal proton-proton coupling constants.
2009The proton magnetic resonance spectra of a series of 2-alkoxytetrahydropyrans of general formula have been measured. R represents a variety of groups, including para-, meta-, and ortho-substituted phenyl, and several alkyl substituents. The geminal coupling constant, JAB, has been determined in each ether, from the AB pattern produced by the ...
