The interaction between the spin of the nucleus and the angular momentum of the electron causes a further (hyperfine) splitting of atomic states. It is called hyperfine because it is also order like the fine structure corrections, but it is smaller by a factor of about because of the mass dependence of the spin magnetic moment for particles. downtown homewood al restaurants

WebFine structure High resolution spectra show that lines have what is called fine structure. For example, the H α line is actually a number of closely spaced lines, spread in wavelength over ≈ 0.02 nm. There are a number of effects which contribute to modifying the energies from the Bohr model predictions. One effect is due to special relativity.
