(p513) number of chemically nonequivalent (p513) One of the greatest advantages of 13 C-NMR compared to 1 H-NMR is the breadth of the spectrum - recall that carbons resonate from 0-220 ppm relative to the TMS standard, as opposed to only 0-12 ppm for protons. Any element with a nuclear spin ( 13 C, 17 O, 19 F, 31 P and many others) will give rise to an NMR signal.Carbon-13 NMR ( 13 C NMR or referred to as carbon NMR) is the application of nuclear magnetic resonance (NMR) spectroscopy applicable to carbon.
