Carbon satellites in physics and spectroscopy, are small peaks that can be seen shouldering the main peaks in the nuclear magnetic resonance (NMR) spectrum. These peaks can occur in the NMR spectrum of any NMR active atom (e.g. 19 F or 31 P NMR) where those atoms adjoin a carbon atom (and … WebAs in the case of 1H NMR, 13C NMR spectra are obtained typically in CDCl 3 with tetramethylsilane (TMS) as internal reference, i.e., δ = 0 ppm for TMS methyl carbons. Most of the 13C NMR chemical shift values fall in the range between 0 and 220 ppm. For representative 13C NMR chemical shifts, see Table 11.2, p. 403 of Ege’s book.
