Abstract : The difference in chemical shift between the methylene protons of a number of compounds related structurally to 1-phenylethyl benzyl ether has been measured. Correlations between structural features of these compounds and the magnitude of the magnetic non-equivalence induced by the center of molecular asymmetry provide basis for qualitative identification of the most important factors contributing to the chemicalshift difference.
