      In the specific case of Cu(II), the nuclear spin of Cu is I = 3/2, so the hyperfine splitting would result in four lines of intensity Similarly, super hyperfine splitting of Cu(II) ligated to four symmetric I = 1 nuclei, such as 14 N, would yield nine lines with intensities would be Full text of "Atomic Spectra & Atomic Structure" See other formats.

Electron Spin-Nuclear Spin Coupling (Hyperfine Structure) Just like an electron, a proton is spin 1/2 and has a magnetic moment. (According to nuclear theory, this moment is due to the orbital motion of quarks within the proton.).

Additional Physical Format: Online version: Tolansky, S. (Samuel). Hyperfine structure in line spectra and nuclear spin. London, Methuen [] (OCoLC)   The hyperfine structure observable in atomic spectra, including the interactions with nuclei, indicates that the nuclei have spin. The nuclear spin is a vector, and its absolute value is I (I + 1) h 2 π, where I is the quantum number of the nuclear spin, simply called nuclear spin.

Richard Cammack, in Encyclopedia of Spectroscopy and Spectrometry, Distances. The hyperfine coupling between an electron spin and a nucleus or between electron spins consists of two components: an exchange interaction (acting through chemical bonds, and generally isotropic), and a dipolar interaction.

The dipolar component is anisotropic and its magnitude is. The hyperfine structure of ns and nd Rydberg states of {sup 83}Kr has been measured in the range n= below the {sup 2}P{sub 3/2} ionization threshold by pulsed-field ionization following single-photon excitation from the {sup 1}S{sub 0} ground state using a narrow-bandwidth vacuum-ultraviolet laser system.

In Fig. 4 the effect of the hyperfine coupling on the energy level diagram and the EPR spectrum is illustrated for the simple case of isotropic EZI and HFI for a spin I = 3/2 (e.g. Cu 2+) 2.

The coupling between the electron and nuclear spin results in a. Background Gross structure. The gross structure of line spectra is the line spectra predicted by the quantum mechanics of non-relativistic electrons with no spin.

For a hydrogenic atom, the gross structure energy levels only depend on the principal quantum number r, a more accurate model takes into account relativistic and spin effects, which break the degeneracy of.

Electron Spin Resonance When the molecules of a solid exhibit paramagnetism as a result of unpaired electron spins, transitions can be induced between spin states by applying a magnetic field and then supplying electromagnetic energy, usually in the microwave range of frequencies.

The resulting absorption spectra are described as electron spin resonance (ESR) or electron. Full text of "Fine Structure in Line Spectra & Nuclear Spin" See other formats.

These are essentially (i) the magnetic interaction of the electron with nuclei of nonzero nuclear spin (hyperfine interaction), which determines the multiline structure of the spectrum (hyperfine.

The two Rb isotopes have different nuclear spin, so the hyperfine splittings of the ground states, and hence the corresponding coupling constants A, are different in the two cases.

N is the number of equivalent nuclei and I is the spin. For example, an unpaired electron on a V4+ experiences I=7/2 from the vanadium nucleus. We can see 8 lines from the EPR spectrum.

When coupling to a single nucleus, each line has the same. As can be seen from a short note by N. Bohr, who first suggested the possibility of a nuclear field effect on the S-term of the series of atomic spectra, (22) people in the s could hardly imagine that optical spectroscopy would provide nuclear-structure information, because Rutherford (4) showed the dimension of the atomic nucleus to be.

Duin 1 EPR, the Technique. • Molecular EPR spectroscopy is a method to look at the structure and reactivity of molecules. • EPR is limited to paramagnetic substances (unpaired electrons). When used in the study of metalloproteins not the.The hyperfine structure of the hydrogen spectrum is explained by the interaction between the magnetic moment of the proton and the magnetic moment of the electron, an interaction known as spin-spin coupling.

The energy of the electron-proton system is different depending on whether or not the moments are aligned.
