Molecular dynamics for the selected channels. Pump-probe delay-dependence of the KER for the channels a OH⁺ + C₂H₅⁺, b H₂O⁺ + C₂H₄⁺, c H₃O⁺ + C₂H₃⁺, and d H⁺ + H₂O⁺ + C₂H₃⁺. For positive delay, the pump and probe pulses have an intensity of 4.2 × 10¹⁴ and 6.7 × 10¹⁴ W/cm², respectively. For the negative delays, the pump and probe pulses reverse roles. The time-independent features at KER ~5 eV for (a–c) and ~13 eV for (d) are mainly due to interaction with only one of the pulses
