Application of 13C NMR spectroscopy in the assignment of 1H NMR signals of nonequivalent SCH3 groups. Proceedings and Transactions of the Nova Scotian Institute of Science, 35(1), 17-25.http://hdl.handle.net/10222/15212The SCH3 groups of 3- and/or 5 alkyl substituted 2,4,6-trithiaheptanes have almost identical chemical shifts in both 1H and 13C nmr spectra. A combination of gated decoupling and single frequency off-resonance decoupling, followed by the construction of graphs of the type proposed by Pachler, allows the assignment of the 1H nmr signals.enSpectrum analysisChemistryText
