Abstract Differences in their IR spectra are used to identify and analyze compounds containing a monosubstituted ethylenic (vinyl) group. Variations in location, shape and intensity of the various bands due to this structure were studied. Although previous work was briefly reviewed, emphasis was on new information obtained from IR spectra of long chain vinyl compounds related to vegetable oils, including 1‐alkenes, acrylic esters, allyl esters and ethers, vinyl esters, vinyl ethers and vinyl ketones. In IR spectra of long chain (C 10 −C 18 ) vinyl compounds bands caused by the vinyl structure show clearly and, usually, without interference. These bands consist of stretching vibrations of the vinyl olefinic bond and the three vinylic C−H bonds, and of in‐plane and out‐of‐plane deformations of the C−H linkages. Since the vinyl group and neighboring groups influence one another, the interactions of vinyl groups with carbonyl groups and single C−O bonds, as in esters and ethers, were investigated.
