Data from the pmr spectra of β-amino-, β-aminohydrochloride-, β-hydroxy-, and β-nitro-α- phenyl-propanes having methyl or methoxy substituants on the phenyl ring (37 compounds in all) are presented. The α and β protons of the side-chain give a pattern usually analyzable as ABX. The data are discussed in terms of correlations of coupling constants and chemical shifts with electronegativity of the substituent groups, steric and electronic effects, and ...
