Studies were made of the infrared absorption spectra of methyl esters of oleic, elaidic, linoleic, linoelaidic, <I>trans</I>-10, <I>cis</I>-12-octadecadienoic, α-eleostearic, stearolic, stearic, 9,10-dideutero-oleic, and 9,10-dideutero-elaidic acids in the C–H stretching region. It was further confirmed that the prominent absorption bands at 3020 cm<SUP>−1</SUP> occurring in the infrared absorption spectra of methyl esters of unsaturated higher fatty acids are assignable to the =C–H stretching vibrations of a <I>cis</I>-ethylenic double bond. The =C–D stretching vibrations of deuteroethylenic double bonds (–CD=CD–) in methyl 9,10-dideutero-oleate and -elaidate occurred at 2250 and 2225 cm<SUP>−1</SUP> respectively.
