✦ Synopsis

Abstract

The ^1^H and ^2^H NMR spectra of a number of edible oils were investigated. The average numbers of hydrogens and deuteriums for the olefinic, methylene and methyl sites in mixtures of triacylglycerols were determined, and some parameters describing the different fractionation of deuterium in the various sites were obtained. These results are discussed in connection with the biosynthesis steps involved in the elongation and desaturation processes of the fatty acid components.

Magic-angle spinning (MAS) 2 H and 17 O NMR spectra were obtained for water, following addition to an activated carbon. Shortly after addition two peaks are seen: a 'free liquid' resonance and a second broad resonance shifted to low frequency. The latter is attributed to water in the pores of the ac
