Vinyl-group-ir-spectra, an infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups. in physical and analytical chemistry, infrared spectroscopy (ir spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is .... 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 ..., 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 t....

Abstract 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..., 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 ....
