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. H O O H 3C WebApr 24, 2012 · Carbon-13 has 6 protons and 7 neutrons, so we can study it with NMR. The structure and C-NMR spectrum of 3,3-dimethyl-2-butanol is shown below. At first glance, the spectrum looks almost the same as the H-NMR spectrum. However, there is little indication of how many carbons a single peak is referring to. perth skyline images
