The BRC has a complex electronic excited state, P*, that evolves into subsequent products P+Hand P+B-. Pump-dump-probe spectroscopy on the wild type BRC and on YM210W, a mutant with a stabilized, long lived P* excited state, has uncovered a new charge-separated state in both BRC’s. When P* is dumped, a fraction of its population is transferred to this state that has a strong Stark shift in the ...
