Figure 7. Oxygen-atom population.
The (ROO, θ) and (ROO, φ) contour maps of the oxygen atom population within the second-shell RDF peak (ROO ≤ 4.5 Å) and the (θ, φ) contour map within the first shell (ROO ≤ 3.4 Å). ROO, θ, and φ are spherical coordinates as defined above. D and A stand for the hydrogen-donating (H-donor) and accepting (H-acceptor) water molecules, respectively.
