Abstract

We demonstrate that the ultrafast relaxation observed in the excited states of large organic molecules in solution may be understood as the coherent evolution of the initially prepared non-stationary state. it is shown that under femtosecond excitation conditions the relaxation is determined by the characteristics of the light pulse. The analysis of a simple pump-probe experiment suggests a way of measuring the characteristics of ultrashort pulses. The case of fluorescence excited by ultrafast is also analysed.
