electronhydrogen-like atomparabolic coordinatesFor the first time, electron transitions in a hydrogen-like atom with changes in the spatial dimension D = 3 -> D ' = 1, 2 and energy of its state accompanied by photon emission are considered. Similar conversions of some atoms have already been...
2.The fittings suggest the absorption in the near IR region is ascribed to at least twoelectronic transition,i.利用精确的单跃迁光吸收公式对Ce:YIG的光吸收谱进行拟合计算,得到近红外区的光吸收至少可归结为两种电子跃迁,跃迁中心分别在1。 3.The results also show that there areelectronic transitions Fe...
A Pi electron refers to unsaturated or multiple bond electrons found in compounds like olefins and carbonyls. These electrons exhibit Rydberg transitions in the 120–180 nm region and are responsible for absorption bands in the visible spectrum. ...
This approach has been applied to electron-hydrogen atom scattering for L=0, S=0, and even parity to give the first accurate cross sections for n=1 and n=2 to n=3 transitions at intermediate energies. The results have important implications for earlier work which overestimates these cross ...
Thermochromic transitions for these polymers appear to be electronically driven, perhaps by polarization forces between the polysilane chain and the side chains.129 Below the transition temperature, the main chain may partially straighten to produce longer trans segments, although the polymers retain ...
Building an electronic device using individual molecules is one of the ultimate goals in nanotechnology. To achieve this it will be necessary to measure, control and understand electron transport through molecules attached to electrodes. Substantial prog
Complex I is a part of the respiration energy chain converting the redox energy into the cross-membrane proton gradient. The electron-transfer chain of iron-sulfur cofactors within the water-soluble peripheral part of the complex is responsible for the d
For a hydrogen-like atom, classify the electron transitions according to whether they result in the absorption or emission of light. Answer Bank ◻ ◻ ◻ ◻ Ignoring sign, which transition is associated with the greatest energy change?
Capture of an electron corresponds to a transition from a curve for a molecule to a curve for an ion (andelectron detachmentcorresponds to a reverse transition). As follows from the Franck–Condon principle (Section 1.4.9), these transitions are represented by vertical arrows. ...
In SnSe the stereoactivity of the 5s2electron lone pair is present. Unique structural transitions have been noted for SnSe. At low temperatures, it crystallizes in the orthorhombicPnmaspace group where Sn is essentially three coordinated (Fig. 16C). This form, termed asα-SnSe, converts to or...
