C NMR spectroscopy suffers from a complications that are not encountered in proton NMR spectroscopy. C NMR spectroscopy is much less sensitive to carbon than H NMR is to hydrogen since the major isotope of carbon, the C isotope, has a spin quantum number of zero and so is not magnetically active and therefore not detectable by NMR.

Due to differential uptake in plants as well as marine carbonates of C, it is possible to use these isotopic signatures in earth science. Biological processes preferentially take up the lower mass isotope through kinetic fractionation. In aqueous geochemistry, by analyzing the δ C value of carbonaceous material found in surface and ground waters, the source of the water can be identified. This is because atmospheric, carbonate, and plant derived δ C values all differ. In bio… WebRemember that each peak identifies a carbon atom in a different environment within the molecule.
