Figure 6
Profiles of ∇2ρ (e Å−5; black squares) and ∊ (%; grey triangles) along the bond paths of (a) the P—P bond and (b) the P—O bond (P is on the left, O on the right). The ellipticities are given for (b) only. The x axis represents the coordinate (in Å) with respect to the bond-critical points (x = 0) along the bond path. |
