    • -1. It is anticipated that this mode is local in character and can not be held responsible for the observed superlinear dependence.

    • note
    • For noninteracting chromophores an increase of ε with n is also expected since, in that case, identical transitions are superpositioned. However, the PPP/SCF calculations indicate that it is indeed the HOMO-LUMO transition of the delocalized system which gains intensity.

    • note
    • PPP calculations on planar structures reveal the same trend as observed for the twisted structures. For planar 1-4, calculated HOMO-LUMO transition energies are 4.89, 4.58, 4.60, and 4.66 eV, respectively, while the HOMO-LUMO gaps are 7.37, 6.85, 6.65, and 6.57 eV. This shows that the observed effects are not due to the nonplanar geometries of 1-4.
