Information Available via NMR

There are three types of easily-accessible information available in NMR spectroscopy:
  1. Chemical shift which provides information about the average effective magnetic field (due to nuclear shielding) present at various locations within a molecule;
  2. Spin-spin coupling (coupling constants and spin multiplicities) which derives from through-bond interactions between spin-active nuclei;
  3. Signal intensity, measured as the integral of the signal, which derives from the number of equivalent nuclei present in a given environment.
Of course, it is possible to garner additional information via other processes, such as the nuclear Overhauser effect (NOE).
