A theoretical study of the nuclear magnetic resonance spectra given by ABCD systems in fused aromatic rings is presented. The symmetry of these systems allowed much simplification and equations developed for an R-AB-X case made possible the allocation of the lines to specific transitions. Examples are given to show how the theoretical treatment makes possible an analysis of observed spectra.
