Femtosecond Stimulated Raman Spectroscopy of Linear Carotenoids
Original language description
Femtosecond stimulated Raman spectroscopy (FSRS) and transient absorption data measured in a single experiment are used to determine the vibronic properties of the S-1 state of linear carotenoids with different conjugation lengths. The Raman band corresponding to the C & boxH, C stretching mode in the S-1 state peaks at 1799 cm(-1) (neurosporene), 1802 cm(-1) (spheroidene), and 1791 cm(-1) (lycopene). Contrary to the ground state C & boxH, C mode, variation of the C & boxH, C stretching mode in the S-1 state is small and does not follow a linear dependence on N. The lifetime of the Raman band matches the S-1 decays obtained from transient absorption, confirming its S-1 state origin. Direct comparison of transient absorption and FSRS signals allowed us to assign Raman signatures of nonrelaxed S-1 and S-0 states. For lycopene, FSRS data identified a component associated with a downshifted ground state C & boxH, C mode, which matches the dynamics of the S* signal observed in transient absorption data.
