Physical Properties of Excited States Jablonski Diagram

10 Physical Properties of Excited States Jablonski Diagram 

Electronically excited states of the molecules are short-lived because of excess energy content and try to deactivate through various photophysical and photochemical processes for return to their original ground states. 

Jablonski diagram illustrates the electronic states, properties and relaxation processes of an excited organic molecule (Fig. 6.4) [3]. The electronic states are arranged vertically by energy and grouped horizontally by spin multiplicity. 

Nonradiative transitions are indicated by squiggly arrows and radiative transitions by straight arrows. 

The electronic states of the molecule and their relative energies. Singlet electronic states are So, S, S2, etc., and triplet electronic states are Ti, T2 etc.
