13C NMR Signal and Chemical Shift tural abundance of the ich is 99.985% of hydrogen Sassi The isotope 18C is another NMR active nucleus. The natural abundance isotope is only 1.1% of carbon atoms compared to the 'H isotope which is 99.985% of atoms. Therefore the intensity of WC peaks is lower. It takes a longer time to obtain a spectrum compared to a 'H NMR spectrum. Adjacent WC - WC splitting does occur. chance of two "C atoms being...

Using Carbon NMR Spectra
Nuclear magnetic resonance (NMR) spectroscopy can be used to
gather information about the structure of a compound. The chemical
shift of peaks in a 1H NMR or a 13C NMR spectrum can be used to
gather information about the types of neighboring functional
groups. The spin-spin splitting pattern in a 1H NMR spectrum can be
used to determine the number of hydrogen atoms on neighboring
carbon atoms.
