UV-Vis (electronic) spectroscopy
... an absorber, atom, molecule, or solid. Emission: A transition from a higher level to a lower level with transfer of energy from the emitter to the radiation field. If no radiation is emitted, the transition from higher to lower energy levels is called nonradiative decay. http://www.chemistry.vt.edu/ ...

Van der Waals Forces Between Atoms
... Waal interaction energy goes as 1/ R 3 , much more important than the 1/ R 6 energy for two hydrogen atoms in the ground state. Notice also that the 1/ R 3 can be positive or negative, depending on whether the atoms are in an even or an odd state—so the atoms sometimes repel each other. Fin ...

Chapter 11 Laser
... Now suppose a beam of radiation is sent through the cell with frequency v corresponding to the energy difference E. The ratio of the numbers nE and n0, that is, the ratio of the populations of the energy levels, will increase. Since the population of the normal state was so much larger than that of ...
