Abstract

A complete analysis of the high resolution proton magnetic resonance spectra of monosubstituted benzaldehydes has been performed as an ABCDE spin system. The chemical shifts and the coupling constants are determined in six compounds with great accuracy. By using the additivity rule the calculated proton coupling constants of benzene are (in Hertz):
