Although scientific knowledge of photolysis and radiolysis of water is widely used in the life sciences and other fields, the formation mechanism of the spatial distribution of hydrated electrons (spur) resulting from energy deposition to water is still not well understood. The chemical reaction times of hydrated electrons, OH radicals, and H $_{3}$ O $^{+}$ in the spur strongly depend on the spur radius. In our previous study, we elucidated the mechanism at a specific given energy (12.4 eV) by first-principles calculations. In the present study, we performed first-principles calculations of the spur radius at the deposition energies of 11-19 eV. The calculated spur radius is 3-10 nm, which is consistent with the experimental prediction (~4 nm) for the energy range of 8-12.4 eV, and the spur radius gradually increases with increasing energy. The spur radius is a new scientific knowledge and is expected to be widely used for estimating radiation DNA damage.

Selective OD bond dissociation of HOD; Photodissociation of vibrationally excited HOD in the 5 $_{OD}$ state

Vibrationally excited HOD in the fourth overtone state of the OD-stretching mode (5 $_{OD}$ ) has been photodissociated by ultraviolet photolysis at ca. 243.1 nm. Branching ratio between the OH- and OD-bond dissociation channels has been determined by detecting the H and D atoms. The OD-bond dissociation is the dominant channel, with the yield of H atom generated by the photolysis being below the detection limit.
