Dark states of astaxanthin bound to LHC–Asta. a Overlay of the SADS of the different Car dark states estimated from the target analysis reported in Fig. 3. b Simplified scheme of the potential energy surface of astaxanthin bound to LHC–Asta. In this representation, S1 is higher in energy than S* and Sq, in accordance with previously published information41. Sq is positioned at the lowest level because it is found to be the only state able to quench Chls in LHC–Asta. For further explanation, see text. The red arrows indicate that Sq, similarly to S*41, 68, originates from twisted conformations of the Car
