Image 3. Weak charge-transfer state, strong charge-transfer state and strongly correlated triplet-triplet pair states must interact in different vibronic regions of compression and stretching. The delocalisation and stabilisation of initial vibronic 1(TT) state leads to the formation of free triplets, facilitating carrier transportation in singlet fission of pentacene.
