title: Comment on "Does the hydrated electron occupy a cavity?".
abstract: Larsen et al. (Reports, 2 July 2010, p. 65) challenged the long-standing model of the solvent geometry surrounding a free electron in water using molecular dynamics simulations based on a newly derived electron-water pseudopotential. We illustrate that, in contrast to the model they used, the true electron-water interaction is repulsive in the region relevant to the reported extended electron distribution, consistent with the cavity model.
