What depopulation pathways occur from the first excited singlet state? For the first excited triplet state?

What will be an ideal response?

  • Answer
There are three main pathways for decay of the first excited singlet state: emitting a photon or fluorescence, non-radiative decay or internal conversion, and intersystem crossing to the triplet state. The first excited triplet state decays by emitting a photon or phosphorescence, and non-radiative decay or internal conversion.
