... This can be interpreted in the framework of which-path-information: • After emission of a photon it is not possible to say which decay path the photon took in the V -system. Thus, the two paths interfere. • In the Λ-system a measurement of the atomic state (it is either in |bi or |ci) reveals infor ...

... Fig. 1(a), except for the weak shoulder peaks, the field synthesized with a 15-fs fundamental (800 nm) pulse and a 25-fs IR (1200 nm) pulse is almost equivalent to a 4-fs fundamental one-color (OC) field, which thus enables precise control of the electronic motion. Moreover, the synthesized pulse co ...

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.
