] (FRET)]]A '''Jablonski diagram''', named after the Polish physicist ], is a diagram that illustrates the ]s of a ] and the transitions between them. The states are arranged vertically by energy and grouped horizontally by ]. ] are indicated by straight arrows and ] by squiggly arrows. The vibrational ground states of each electronic state are indicated with thick lines, the higher vibrational states with thinner lines. |

Radiative transitions involve the absorption, if the transition occurs to a higher energy level, or the emission, in the reverse case, of a ]. Nonradiative transitions arise through several different mechanisms, all differently labelled in the diagram. Relaxation of the excited state to its lowest vibrational level is labelled ] in the diagram. This process involves the dissipation of energy from the molecule to its surroundings, and thus it cannot occur for isolated molecules. A second type of nonradiative transition is ] (ic), which occurs when a vibrational state of an electronically excited state can couple to a vibrational state of a lower electronic state. A third type is ] (isc); this is a transition to a state with a different spin multiplicity. In molecules with large ], intersystem crossing is much more important than in molecules that exhibit only small spin-orbit coupling. This type of nonradiative transition can give rise to ]. |
