<jats:p> Larsen <jats:italic>et al</jats:italic> . (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. </jats:p>

<jats:p>Turi and Madarász and Jacobson and Herbert argue that the pseudopotential we derived for the hydrated electron contains inaccuracies that make it overly attractive. We show that our potential is derived correctly and argue that the criticisms presented are not relevant when evaluating a pseudopotential’s accuracy for condensed-phase simulation. Neither critique addresses our central result that the experimental properties of the hydrated electron are consistent with a noncavity picture.</jats:p>

<jats:p> Larsen <jats:italic>et al</jats:italic> . (Reports, 2 July 2010, p. 65) suggest that, contrary to the established paradigm, the aqueous electron does not carve out and occupy a cavity in liquid water. Closer examination of their theoretical model, however, reveals that many of its predictions differ substantively from established benchmarks and that its behavior differs qualitatively from Hartree-Fock theory, upon which the model is based. </jats:p>
