• Infrared absorption spectra of polyunsaturated fatty acid esters obtained from cuttle fish oils, showed a characteristic absorption at 1395cm<SUP>-1</SUP>, in addition to the typical absorption of normal fatty acid methylesters. This absorption at 1395cm<SUP>-1</SUP> was related to the double bond, since by hydrogenation or autoxidation it was vanished away.<BR>Methyl linoleate, -linolenate and -arachidonate gave the suitable absorption at this wave number, while methyl oleate, -eleostearate and cyclododecatrien didn't.<BR>This characteristic absorption was assigned to the C-H bending vibration of the center methylene of divinylmethan radical (=CH·CH<SUB>2</SUB>·CH=).
