Simulating electric field interactions with polar molecules
... Raman transitions between ro-vibrational states with the same parity. For field-free orientation, both even- and odd-parity angular momentum states must be coherently excited. This has been demonstrated experimentally using non-resonant, intense two color laser pulses30–32, linearly polarized pulses ...

Coupling Electrons, Phonons, and Photons for Nonequilibrium
... cross-plane momentum in a GaAs-based midinfrared quantum cascade laser. The excess phonons exist only near the Brillouin zone center, but their population is drastically higher than in equilibrium. They strongly affect electronic transport, largely by amplifying electron scattering with phonon absor ...

... This energy excites the gas atoms, which emit the energy as light, but mainly as ultra violet light. The emitted light photons collide with a fluorescent powder that is coated on the inside of the tube. The various atoms in the powder are excited, the electrons jump up to higher energy levels, fall ...

Surface-Enhanced Raman Scattering in Noble
... small noble-metal nanoparticles. We demonstrate that, αp = R3 ²−1 ²+2 is the particle polarizability, R is its rain nanometer-sized particles, SERS is determined by a dius, and ²(ω) is metal dielectric function. The farcompetition between two distinct quantum-size effects: field of molecular dipole, ...

Franck–Condon principle
The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
