What is triplet triplet annihilation ?

Triplet-triplet annihilation is an energy transfer mechanism between two molecules in their triplet state, and is related to the Dexter energy transfer mechanism. Triplet-triplet (TT) energy transfer requires two molecular fragments to exchange electrons that carry different spin and energy. In this paper, we analyze and report values of the electronic coupling strengths for TT energy transfer.

What is the Franck Condon factor?

According to the Franck–Condon principle, the intensity of a vibrational peak in an electronically allowed transition is proportional to the absolute square of the overlap integral of the vibrational wave functions of the initial and final states. This overlap integral is known as the Franck–Condon factor.
