We investigated the behavior of fluorene (C 13 H 10 ), a three-ring polycyclic aromatic hydrocarbon, under the influence of strongfield laser pulses and provided a complete disentanglement and characterization of the photochemical dynamics of fluorene in these photochemical conditions. Excitation by intense IR pulses tends to induce more secondary fragmentation and double and triple ionization than single-photon XUV ionization, which is seen from the recoil-frame covariance analysis and pump-probe dynamics. The strong-field excitation also opens new channels that were not observed in the XUV ionization. First of all, this is the dynamics of the near-threshold neutral molecule, which produces previously unobserved features appearing from the presence of the excited neutral molecule. The second new observation is the tetracation formation, which was observed via the (2,2) channel of the dicationic fragments C 7 H 2+ x and C 11 H 2+ x . All the observed time-dependent channels in photoion and photoelectron spectra were included in a global fit. This fitting dataset consisted of 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. From this analysis, we extracted 60 transient lifetimes corresponding to different photoinduced intermediates. This extensive dataset of the transient species' lifetimes of a prototypical polycyclic aromatic hydrocarbon provides new insights into the rich photochemistry of PAHs under the influence of intense electric fields.
