Delocalizing Electrons in Water with Light Academic Article uri icon

abstract

  • Experimental information on the spatial extent of the putative p and conduction band states of the hydrated electron (eeq)has been obtained by monitoring and controlling the electron/hole spatial separation of a photogenerated eeq/hole pair using a femtosecond laser pulse sequence. Optical excitation of eeq with two photons is observed to dramatically alter its spatial distribution and geminate recombination yield with the hole. One-photon excitation, in contrast, has no effect on the spatial distribution. The results strongly confirm theoretical predictions on the size and location of excited states of eeq.
