The near IR spectra of a series of compounds derived from long chain fatty acids and containing the vinyl structure were examined. These included 1‐alkenes; acrylic, allyl and vinyl esters; and allyl and vinyl ethers. The bands caused by the vinyl structure were observed clearly and usually without interference. These bands consist of overtones of the fundamental C‐H stretching vitrations found in the normal IR region and of combination bands. Interactions between the vinyl group and the rest of the molecule were observed by changes in location, shape and intensity of the near IR bands. Quantitative analysis for vinyl derivatives based on near IR bands is usually convenient.
