www.saplinglearning.com898 CHAPTER 19 • THE CHEMISTRY OF ALDEHYDES AND KETONES. CARBONYL-ADDITION REACTIONS C. Carbon NMR Spectroscopy The most characteristic absorption of aldehydes and ketones in 13C NMR spectroscopy is that of the carbonyl carbon, which occurs typically in the d190–220 range (see Fig. 13.20, p. 624).

NMR Spectroscopy of Aromatic Compounds (#1e)
www.unm.edu40 13C NMR Spectroscopy of Aromatic Compounds As with other 13C NMR spectra, aromatic compounds display single lines for each unique carbon environment in a benzene ring. Aromatic carbons appear between 120-170 ppm. The 13C NMR spectra of bromobenzene and p-bromoethylbenzene are shown below for comparison.There are four different carbon environments in bromobenzene, and four …

Infrared Spectroscopy and Mass Spectrometry
crab.rutgers.eduInfrared Spectroscopy and Mass Spectrometry Introduction It is fundamental for an organic chemist to be able to identify, or characterize, the new compound that he/she has just made. Sometimes this can be achieved by a chemical means, such as determining the elemental composition and molecular weight.
