Answer to Question #284238 in Organic Chemistry for Reens

Question

how are the energies of excited molecules from the triplet state dissipated?draw a jablonki diagram to depict energy change during these processes

Answer 1

The excited state energy can be dissipated non-radiatively as heat (illustrated by the cyan wavy arrow in Figure 1), the excited fluorophore can collide with another molecule to transfer energy in a second type of non-radiative process (for example, quenching, as indicated by the purple wavy arrow in Figure 1), or a phenomenon known as intersystem crossing to the lowest excited triplet state can occur.
