The use of a pseudo contact shift reagent, (Eu[fod] 3 ), to obtain simplified NMR spectra of a typical long chain monounsaturated fatty acid methyl ester, methyl petroselinate, is described. Spectra were obtained in which individual methylene groups are identifiable from their splitting patterns. Non‐equivalent splitting patterns were observed for the methine protons with varying amounts of reagent used. The effect of concentration of the shift reagent on the chemical shift is discussed.
