UED ionized water (IMAGE) DOE/SLAC National Accelerator Laboratory Caption To observe the short-lived hydroxyl-hydronium pair, the researchers created 100-nanometer-thick jets of liquid water and ionized the water molecules with intense laser light (red beam). Then they probed the molecules with short pulses of high-energy electrons (blue beam) from MeV-UED to generate high-resolution snapshots of the ionization process. This allowed them to measure bonds between oxygen atoms as well as bonds between oxygen (red circles) and hydrogen (white circles) atoms at the same time, thus capturing this important but unstable complex (blue and green).
