To further explore the magnitudes of σ * OH occupations in e - (aq) , we found it revealing to project the distribution of occupations onto the e --oxygen distance and e --O-H angle, where the excess electron's position is taken to be the centroid of the SOMO. This is shown as the false color map in Fig. . Rather surprisingly, we see σ * by the σ * OH orbitals having greatest amplitude on the hydrogen atom side, which then due to phase matching, constructively interfere with the cavity orbital when they point towards the cavity (see Fig. ). This is further confirmed by plotting transition densities between the Cav s and the closest σ * OH orbitals, which are seen to point from the hydrogen atoms towards the center of the cavity (see Fig. ).
