N2 - Ultrafast dynamics of the optically allowed S2 (1 1 Bu+) 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 is determined eliminating effect of excess vibrational energy. The lifetime has a maximum for n = 9 and shows anomalous dependence on the energy gap between the S2 and S1 states.
