Figure Lengend Snippet: (a) Steady-state absorption spectra of the LH2 complex and spheroidene (SPH) in DMSO and n -hexane solution; the inset shows the LH2 complex structure from Rhodobacter sphaeroides 2.4.1 . (PDB:7PBW). The ground state FSRS spectra of spheroidene in n -hexane (b), LH2 complex (c), and DMSO (d).
Article Snippet: An actinic pump, which is at 480 nm for the experiment of spheroidene in n -hexane solution, 500 nm for the experiment of spheroidene in DMSO solution and 510 nm for the experiment of the LH2 complex, is generated using an optical parametric amplifier (OPerA Solo, Coherent, Inc.).
