Some isotopes of Phosphorus and Nitrogen can be studied by this method, but most commonly it is applied to carbon and hydrogen, for which the Larmor frequency varies from 80 to 800 MHz, and tetramethylsilane is the standard.
The time domain variation of this procedure can be used to probe dynamics in solution, and the continuous wave form may either hold the magnetic field constant and vary the frequency, or vice versa. The primary interference is J coupling, which can be accounted for by Pascal's Triangle.

For 10 points, name this process that measures chemical shift--the response of the spin in certain atoms to an applied magnetic field.
