The theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding the electric monopole) with internally generated fields. The theory is derived first for the atomic case, but can be applied to each nucleus in a molecule. Following this … Meer weergeven In atomic physics, hyperfine structure is defined by small shifts in otherwise degenerate energy levels and the resulting splittings in those energy levels of atoms, molecules, and ions, due to electromagnetic … Meer weergeven Hyperfine interactions can be measured, among other ways, in atomic and molecular spectra and in Meer weergeven • Dynamic nuclear polarisation • Electron paramagnetic resonance Meer weergeven The first theory of atomic hyperfine structure was given in 1930 by Enrico Fermi for an atom containing a single valence … Meer weergeven Astrophysics As the hyperfine splitting is very small, the transition frequencies are usually not located in … Meer weergeven • The Feynman Lectures on Physics Vol. III Ch. 12: The Hyperfine Splitting in Hydrogen • Nuclear Magnetic and Electric Moments lookup Meer weergeven Web2 feb. 2013 · Fine structure of esr spectra • Zero Field Splitting • Kramer’s theorem • Effective spin state • Break down of selection rule ... two transitions (or absorptions) can be observed.
