Dark excited states of carotenoid in light harvesting complex probing with femtosecond stimulated Raman spectroscopy

Vibrational dynamics of dark excited states in carotenoids have been investigated using tunable Raman pump pulses. The S sub(1) state has same vibrational dynamics in light-harvesting complex (LH1) and solution. The S super(*) state in LH1 has similar vibrational modes with the triplet state of caro...

Zusammenfassung:Vibrational dynamics of dark excited states in carotenoids have been investigated using tunable Raman pump pulses. The S sub(1) state has same vibrational dynamics in light-harvesting complex (LH1) and solution. The S super(*) state in LH1 has similar vibrational modes with the triplet state of carotenoid. However, the so-called S super(*) state in solution does not have the modes and is concluded to be different from the S super(*) state in LH1.
