    • For the case of the methyl protons 19′ and 20′ an average position was estimated assuming free rotation around the C9′-C19′ and C13′-C20′ single bonds.

    • In principle the presence of the s-cis folded conformation should be evident in the NMR data; however, if its lifetime were shorter that the integration time of the NMR experiment, its detection would be precluded. Consequently the lack of evidence for the presence of this folded conformation in the NMR data does not rule out its existence.

    • This analysis is valid provided that the interconversion of the isomers is slow on the time scale of the fluorescence lifetime. Since the fluorescence decay and s-cis/trans isomerization processes considered here are in the order of a few nanoseconds and tenths of microseconds, respectively, this condition is easily met

    • A rigorous analysis predicts different internal reorganization energies for 1 and 2; however the similar dimension and structure of their carotenoid moieties suggest that taking λi to be equal for both systems is a reasonable approximation
    • i to be equal for both systems is a reasonable approximation.
