      abstract     = {We present an investigation of the ultrafast dynamics of
                      the polycyclic aromatic hydrocarbon fluorene initiated by an
                      intense femtosecond near- infrared laser pulse (810 nm) and
                      probed by a weak visible pulse (405 nm). Using a
                      multichannel detection scheme (mass spectra, electron and
                      ion velocity-map imaging), we provide a full disentanglement
                      of the complex dynamics of the vibronically excited parent
                      molecule, its excited ionic states, and fragments. We
                      observed various channels resulting from the strong-field
                      ionization regime. In particular, we observed the formation
                      of the unstable tetracation of fluorene, above-threshold
                      ionization features in the photoelectron spectra, and
                      evidence of ubiquitous secondary fragmentation. We produced
                      a global fit of all observed time-dependent photoelectron
                      and photoion channels. This global fit includes four parent
                      ions extracted from the mass spectra, 15
                      kinetic-energy-resolved ionic fragments extracted from ion
                      velocity map imaging, and five photoelectron channels
                      obtained from electron velocity map imaging. The fit allowed
                      for the extraction of 60 lifetimes of various metastable
                      photoinduced intermediates.},
