It details how a proton in a molecule, surrounded by circulating electron density, experiences a smaller effective magnetic field due to the induced magnetic field opposing the applied one. This phenomenon, called shielding, affects the energy difference between the alpha and beta spin states, and consequently, the frequency absorbed by the proton.
