✦ Synopsis

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.

The proton and carbon NMR spectra of eight 5-substituted acenaphthenes were obtained. The 13C chemical shifts of C-6 and C-2a of these compounds were compared with those of carbons located at structurally similar positions in 1-substituted naphthalenes (viz. C-8 and C-4). The 13C chemical shifts of

## Abstract ^13^C NMR spectra of unsubstituted 1,6,6aλ^4^‐trithiapentalene and a series of methyl and phenyl substituted 1,6,6aλ^4^‐trithiapentalenes have been recorded. The spectra have been assigned by comparison with ^1^H NMR data based on coupling constants from undecoupled spectra. From the ch
