Comparison of the dipolar and configurational characteristics of the low-lying excited singlet states in peridinin (left) and S-2-peridinin (right) for the relaxed S₁ geometries in methanol. The properties were calculated using SAC-CI methods including full single and partial double configuration interaction using level three integral selection. The effect of solvent was calculated using PCM methods (see text). Calculations were based on the model compounds shown in Fig. 1B.
