<jats:p> The effects of para substituents on the chemical shifts of the diastereotopic benzylic protons in three series of chiral molecules have been determined from a study of the 100 MHz spectra of these molecules in deuterochloroform. The results show that the slope, ρ, obtained from a plot of τ vs. Hammett σ constant, is influenced by a number of factors and that the conformational disposition of the benzylic proton with respect to the aromatic ring is not a dominant factor. </jats:p>
