WebBecause the resolution in 13C NMR is excellent, the number of peaks in the spectrum is a measure of the carbon count adjusted for the symmetry of the molecule. For example, hexane gives three peaks: the two methyls are equivalent as are two sets of methylenes. WebUsing the simplified table of chemical shifts above, work out the structure of the compound with the following 13 C NMR spectrum. Its molecular formula is C 4 H 10 O. Let's sort out what we've got. There are four peaks and four carbons. No two carbons are in exactly the same environment.
