THE NUCLEAR MAGNETIC RESONANCE SPECTRA OF PARA-SUBSTITUTED PHENOLS

Abstract

The nuclear magnetic resonance spectra of a number of para-substituted phenols have been examined. The —OH chemical shifts, extrapolated to infinite dilution in benzene and in carbon tetrachloride, were found to be almost independent of the nature of the ring substituent. Approximately linear relationships were observed between the internal chemical shift of the ring protons and other physical properties.
