Chemical shifts are reported for long-chain acids, methyl esters, glycerol esters, wax esters, nitriles, amides, alcohols and acetates. These indicate the possibility of using high-resolution ]3C NMR spectroscopy for the analysis of mixtures of these types of compound.
H and 13C chemical shift assignments, obtained with the aid of two-dimensional heteronuclear shift correlation and doublequantum coherence ' 3C-INADEQUATE experiments, are reported for four retinoic acid ester isomers observed at the photostationary state. Also detailed are ' H assignments for three
