This chapter deals with the Russell-Saunders coupling (LS-coupling) between the azimuthal momentum and the spin momentum of the electron which jumps up/down in an optical transition, in order to explain the spectral term splitting and the selection rule for the transition. They are important ...

Structure of Matter To understand the process of emission or absorption of light, knowledge of the structure of matter is necessary. For this purpose, we use a very model-like concept (Bohr’s atomic model) to clarify the principle. All matter is built from atoms. An atom is the smallest...

One of the greatest discoveries leading to the formulation of the wave equation of Schrödinger in 1926 was the wave-particle duality principle formulated by Louis de Broglie in 1923; this principle expresses states that atomic and subatomic particles (matter) and photons (energy) exhibit both wav...

Note that thePauli exclusion principleis not related to any interaction: if we could switch off the Coulomb repulsion between electrons (but leave intact their attraction to the nuclei), no serious changes inatomic physicswould occur, although some revision of the Periodic Table would be needed. ...
Due to the large surface area to volume ratio, atomic functionalization by surface adsorption has been considered as a feasible and common method to manipulate electronic, magnetic, and chemical properties of 2D materials. Numerous computational and experimental studies have been carried out to ...
an active powder purified by XAD-2 and then by column chromatography on Sepadex LH-20 was subjected to atomic absorption spectrophotometry for sodium and to elementary analysis for nitrogen. The results were, calcd. for C27H47O9SNa, Na;4.03, N;0.00, found Na;3.57, N;0.02. The stereochemist...
An application of the maximum principle to the study of essential self‐adjointness of Dirac operators. I We formulate a theorem saying that the Dirac operator corresponding to a one‐electron atomic ion is essentially self‐adjoint on the usual domain, provide... JJ Landgren,PA Rejto - 《Jour...
