    • note
    • In photoinduced absorption spectroscopy singlet excitations are created by strongly absorbed light. These singlet excitations can evolve into triplet excitations or dissociate to yield racidal cations and radical anions. The relative change in transmission upon photoexcitation is then monitored as a function of wavelength.

    • note
    • In materials in which a vibronic progression of the absorption is resolved, the calculated excitation energy corresponds to the maximum of the envelope of the absorption spectrum rather than to the vibronic 0-0 transition.

    • note
    • We have used Zerner's intermediate neglect of differential overlap (ZINDO) coupled to a configuration interaction (CI) scheme to calculate the excitation energies on the converged b31yp/6-311g(d,p) geometries scaling the CI active space with the number of pi-conjugated carbon atoms, which is a prerequisite for size consistancy with the CI method.
