The chemical structures of the carotenoid molecules are very simple and one might think that their electronic features are easily predicted. However, there is still has so much unknown information excepting the correlation between the electronic ener

The formation and relaxation of plasmon-induced hot electrons in Au nanodisks (AuNDs) with relatively large particle size was studied by femtosecond pump-probe spectroscopy. We temporally resolved the plasmon-induced formation of nonthermal electrons

Three organic semiconductors consisting of thiophene, furan, and phenylene groups showed either one or two gain-narrowed emission peaks by excitation with a laser pulse. The two gain-narrowed emission peaks are optically studied and assigned to 0 →

The ultrafast structural dynamics in the electronic excited state of photoactive yellow protein (PYP) is studied by femtosecond stimulated Raman spectroscopy. Stimulated Raman spectra in the electronic excited state, S(1), can be obtained by using a

In photosynthesis, carotenoids play important roles in light harvesting (LH) and photoprotective functions, which have been described mainly in terms of two singlet excited states of carotenoids: S(1) and S(2). In addition to the "dark" S(1) state, a

Femtosecond one- and two-photon pump–probe dispersive spectroscopic measurements have been applied to the investigation of the vibrational relaxation kinetics of the dark S1 (21 A g - ) state in β-carotene, combining a higher sensitive detection s

Dark excited states of carotenoid in LH1 complex have been investigated by measuring recovery dynamics following the repump. The S* state in LH1 is different from the S1 state but is similar to the T state.

Ultrafast dynamics of the optically allowed S 2 ( 1 1 B u + ) state in all-trans-carotenoids with a number of conjugated double bonds, n = 7–15, has been investigated by femtosecond Kerr-gate fluorescence spectroscopy. The lifetime of the S2 state

Ultrafast optical phenomena in all-trans-β-carotene have been investigated by femtosecond absorption and fluorescence spectroscopy. Following a resonant pump pulse, both fluorescence and absorbance changes have a decay time of 150 fs. The signals ar
