The transient structures at different time instants from the X, A and C states are firstly given based on the simulations in the current condition. For example, the ROD stretches from 97 pm to 107 pm along the A state within approximately three optical cycles, and further extended to 116 pm evolving along the ground state of the dication within 2 fs (electron recollision time). In the lower panels, the retrieved geometry of neutral water on average is 101∘-96 pm. The simulations indicate that after ultrafast relaxation within 5 fs along the autoionisation state of dication, the ROD stretched to 163 pm for the Auger decay pathway.
