الوصف: | The 1H- and 13C-NMR spectra of dinaphtho[1,2-b:1′2′-d]thiophene (1), a sulfur-containing polynuclear heteroaromatic, have been totally assigned using a combination of two-dimensional NMR techniques. Techniques applied were standard proton-proton COSY, proton zero-quantum coherence (ZQCOSY, optimized to 7 Hz and to 1.75 Hz), proton double quantum coherence (DQCOSY, optimized to 7 Hz), broad-band decoupled (both dimensions) proton-carbon chemical shift correlation, long-range proton-carbon chemical shift correlation, and proton-carbon heteronuclear relayed coherence transfer. A comparison of these methods on 1 showed the most useful information concerning connectivities to be obtained from the zero-quantum coherence and long-range heteronuclear correlation experiments. A detailed critique of each type of experiment is given in the context of applications to polynuclear aromatics. |
