Results for ammonia, methanol and water clusters investigating the dynamics upon XUV ionization with the FERMI free electron laser are presented. In an XUV-UV pump-probe scheme we obtain a time-resolved picture of the resulting fragments and their electronic states. Recombination and molecular dissociation lead to a great variety of electron energies and ionic fragments that give insight into the underlying dynamics. The vertical detachment energies of the electrons and masses of the ions were measured by means of a VMI velocity map imaging detector combined with a time-of-flight mass spectrometer which also allows a covariance analysis.
