Figure 1.
(A) Structures of peridinin and analogues and (B) ground state vacuum geometries of the model chromophores used to represent peridinin, S-1-peridinin and S-2-peridinin in the theoretical studies. Ground state (vacuum) dipole moment vectors and magnitudes are shown. Geometries and dipole moments were generated using B3LYP/6-31G(d) density functional methods.
