(a) The TOF spectrum of recoil ions. (b) Two-dimensional TOF coincidence spectrum of charged fragments. Enlarged map is the Coulomb explosion process of N₂O²⁺. The first slash line I centered at (3.90, 5.71) is from the de-nitrogenation photodissociation channel. Here, the x-axis value shows the TOF of N⁺ fragments while the y-axis value shows the TOF of NO⁺. The second slash line II at (4.17, 5.52) is the de-oxygenation photodissociation channel in which the x-axis value is the TOF of O⁺ fragment and the y-axis value is that of N₂⁺ fragment.
