Fatty acids, part 15. Nuclear magnetic resonance spectra of the CIS octadecenoic acids and of some acetylenic acids

Add time:08/08/2019    Source:sciencedirect.com

The N.M.R. spectra of the cis octadecenoic (Δ2–Δ17), octadecynoic (Δ2–Δ5, Δ10), and dodecynoic (Δ5–Δ11) acids have been recorded. Those with unsaturation near the centre of the molecule cannot be distinguished from one another but the four isomers with unsaturation closest to the carboxyl group and the four with unsaturation closest to the methyl group show distinctive spectral features which allow them to be identified.
