Water-structure based mechanistic view on the bimolecular decay of the hydrated electron

- Water-structure based mechanistic view on the reaction of two e−aq is presented.
- Proton transfer occurs when two e−aq occupy neighbouring cavities in HB network.
- The formation of H2 results from backward scattering in rigid HB network.
- Puzzling behaviour of e−aq reveals change in connectivity of hydrogen-bonds above 150 °C.
