Figure 4: Transient optical absorption data.
From: Unified model for singlet fission within a non-conjugated covalent pentacene dimer
(a) Species-associated transient absorption difference spectra for NC obtained at 295 K in benzonitrile using the kinetic model given in Fig. 3. Inset: single wavelength kinetics and fits to the data. (b) Population kinetics for each species. (c) Species-associated transient absorption difference spectra for NC obtained at 105 K in butyronitrile using the kinetic model given in Fig. 3. Inset: single wavelength kinetics and fits to the data. (d) Population kinetics for each species. The total number of T1 states per S1 created is twice the population of the T1 species indicated in b,d. Multiplying the species-associated spectra in a,c by the corresponding species populations in b,d, respectively, yield the complete ΔA versus time and wavelength data set.
