    Ultrafast optical responses of three-level systems in β-carotene: Resonance to a high-lying n 1 A g − excited 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...
