Abstract The proton and carbon NMR spectra of several 4‐substituted‐ and 4,6‐disubstituted‐dibenzothiophenes have been measured, and their chemical shifts assigned employing spin decoupling and COSY and HETCOR two‐dimensional techniques. This work rectifies several literature misassignments of 13 C chemical shifts of 4‐substituted dibenzothiophenes and also examines the effects of substituents on the chemical shifts. Hence this study will be useful in the future structure determinations of mono‐ and multisubstituted dibenzothiophenes.
