      abstract     = {Photoionization can initiate structural reorganization of
                      molecular matter and drive formation of new chemical bonds.
                      Here, we used time-resolved extreme ultraviolet (EUV) pump
                      – EUV probe Coulomb explosion imaging of carbon dioxide
                      dimer ion $(CO_2)_2^+$dynamics, that combined with ab initio
                      molecular dynamics simulations, revealed unexpected
                      asymmetric structural rearrangement. We show that ionization
                      by the pump pulse induces rearrangement from the
                      slipped-parallel (C$_{2h}$) geometry of the neutral $CO_2$
                      dimer towards a T-shaped (C$_{2v}$) structure on the
                      ~100 fs timescale, although the most stable
                      slipped-parallel (C$_{2h}$) structure of the ionic dimer.
                      Moreover, we find that excited states of the ionized $CO_2$
                      dimer can exhibit formation of a $CO_3$ moiety in the
                      $CO_2O_4^+$ complex that can persist even after a suitably
                      time-delayed second photoionization in a metastable
                      $CO_2O_4^+$ dication. Our results suggest that charge
                      asymmetry plays an important role in the ionization-induced
                      dynamics in such dimers that are present in $C_2$ rich
                      environments.},
