The above shows the ?-electronic energy levels of an organic molecule.
2.
This paper reported the first-ever single electron spectroscopy work in which electronic energy levels of atoms at the surface of a metal were observed.
3.
Thus, when a material is illuminated, individual photons of light can make the valence electrons of an atom transition to a higher electronic energy level.
4.
For example, the emission spectrum of a gas-discharge lamp can be altered by filling it with ( mixtures of ) gases with different electronic energy level configurations.
5.
Thus, because vibrational and rotational energy levels are more closely spaced than electronic energy levels, heat is more easily transferred between substances relative to light or other forms of electronic energy.
6.
B " T " ( roughly 0.025 eV ) is much smaller than the spacing between the lowest and next higher electronic energy levels ( roughly 10 eV ).
7.
James Franck recognized that changes in vibrational levels could be a consequence of the instantaneous nature of excitation to higher electronic energy levels and a new equilibrium position for the nuclear interaction potential.
8.
:: : That article suggests that'bands'are simply a term used to describe the electronic energy levels of a solid when lots of atomic orbitals ( with similar but slightly different energy levels ) come together.
