N2  - The assignment of the chemical shifts of dibenzothiophen is presented as well as an analysis of the spectra of the sulphoxide and sulphone. A small inter-ring coupling exists in these compounds and also in dibenzoselenophen. The solvent dependence of the chemical shifts of dibenzothiophen has been briefly investigated but cannot be explained in simple terms.
