WebbThe 1 H-NMR spectrum of the C 18 fatty acid methyl ester methyl petroselinate (Fig. 4), in which the cis double bond is located at C6, however, shows minor changes in the chemical shifts compared to methyl oleate, such as the fine structure of the signals of the olefinic protons and a slight downfield shift of the triplet caused by the C2 protons. WebbThe 14 p -electron bridged annulene on the left is an aromatic (4n + 2) system. It forms a dianion which is a 16 p -electron (4n) system. In the nmr spectrum of the dianion, the innermost methylene protons (red) give an nmr signal at +22.2 ppm, the adjacent methylene protons (blue) give a signal at +12.6 ppm, and the methyl protons (green) a ...
