Magnetism electronic energy levels

Three quantum numbers had been proposed, based on spectral lines and inferences about electron energy levels a principal quantum number to specify energy level of the atom an azimuthal quantum number to specify the angular momentum of electrons moving elliptically and an inner or magnetic quantum number to express the orientation of the plane of the electron s orbit in a magnetic field. 20... 

Fig. 10. Photoeleotron spectrum of oxygen using the helium resonance line (21-21 e.v.) obtained with a magnetic electron energy analyser (May and Turner, unpublished work). Ionization energy increasing from left to right. The spectrum reveals four levels of ionization and the vibrational structure associated with each state of the ion can be clearly distinguished. This spectrum may be compared with that obtained using an electrostatic retarding field analyser (Al-Joboury et al., 1965).

An added dimension to research on nanocrystals is their size-dependent properties. The electronic, magnetic and optical properties of a nanocrystal depend on its size [4]. In small nanocrystals, the electronic energy levels are not continuous as... 

Fig. 5. As the applied magnetic field increases in strength, the electronic energy levels split at a rate given by the "g-value". At resonance, the energy of the micro-wave quantum matches the energy separation between the states and can be absorbed...

Although the lanthanides can possess up to 14 identical f-electrons, each rare earth differs from the others in its optical and magnetic properties. For the general case, in terms of effective radius, , we have the following relation of electronic energy levels, shown as follows ... 

Jahn-Teller effect - An interaction of vibrational and electronic motions in a nonlinear molecule which removes the degeneracy of certain electronic energy levels. It can influence the spectrum, crystal structure, and magnetic properties of the substance.
