1)
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.
The chemical shift (?) of an atom is influenced by the
electrons...
