The bleaching dynamics of organic dye molecules in solution have been investigated using 70 fs pulses from a colliding pulse mode-locked ring dye Laser. In addition to ground state relaxation on a nanosecond time scale, a fast partid recovery 1s observed. For the dyes Nile blue, oxazine 720, cresyl

Ultrafast relaxation in the fluorescent state of 4-(dicyanomethylene)-2-methyl-6-(pdimethylaminostyry1)-4H-pyran (DCM) has been interrogated by time-resolved femtosecond absorption spectroscopy both in methanol and in ethylene glycol. Following a subpicosecond rise, each frequency-specific trace in
## Rcceivcd 21 Jl?ly 1975 We present a theoretical model for describing spin coherence in photoexcited triplet states in zero-field under the influence of vibronic relaxation. From a comparison with experimental results in parabenzoquinone we obtain information about the properties of the excited
