Using the intense and ultrashort light pulses provided by the free-electron laser FLASH at DESY in Hamburg, it has been possible for the first time to observe fast dynamical processes in individual highly excited molecules as a function of time. By means of the pump-probe technique, where a molecule is excited by a first pulse and subsequently probed by a second delayed pulse, the mechanisms can be uncovered that proceed within a molecule or during its break-up [1]
