Abstract
The experimental absorption spectra of J-aggregates of the carbocyanine dye THIATS and TDC were fitted to a segment and a continuous energy disorder (CED) model. From 6 K to room temperature the best fits were obtained using an exponential distribution of segment lengths. Both models gave equally good fits when the average length in the segment model corresponded to the average localization length in the CED model. At room temperature homogeneous broadening or/and an enhanced contribution of the off-diagonal disorder must be taken into account.
