This table lists the locations and intensities of absorptions produced by typical functional groups. Comparison of spectra of aldehyde and ketone 35. 2.2.1. Fig. IR Spect: Drawing Spectra - Organic Chemistry Video | Clutch Prep Aldehydes are used for the manufacture of synthetic resins, such as bakelite, and for making dyestuffs, flavorings, perfumes, and other chemicals. Infrared spectroscopy - spectra index . Finally, an aldehyde group would result in a chemical shift of δ=9 - 10 ppm (choice C is incorrect). Why? All three compounds show much . IR Spectra: IR: 1471 (Sadtler Research Laboratories Prism Collection) Hazardous Substances Data Bank (HSDB) 4.4.1 FTIR Spectra. The characteristic bands for the carboxylate are in the range of 1510-1650 cm-¹ for the asymmetrical vibration and 1280-1400 cm-¹ for the symmetrical vibration.21,28 In the case of sodium oleate, it was found that the symmetrical and asymmetrical bands were located at about 1440 and 1560 cm-¹ from ex-situ diffuse reflection spectra (not .
