Fig. 1: XUV pulse only data.

Ion mass spectra for the three PAH molecules, pyrene (PYR), phenanthrene (PHE), and fluorene (FLU), after irradiation with the XUV pulse at 30.3 nm, in green, red, and blue respectively. Intensities are normalized on the height of the respective parent ion PAH+. Insets show the velocity-map images for the PAH2+ dication and C2H\({}_{x}^{+}\) for FLU (four-fold symmetrization about the laser polarization and vertical axis applied).
