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.
