Figure 3
Bond CP properties versus the B—O, Si—O and Ca—O bond lengths (expressed in Å). Rhombi mark the ab initio points (Downs et al., 2002). Circles mark datolite points. (a) Plot of Rb(O) (bonded radii) versus bond lengths. (b) Plot of ρ(rcp), expressed in e Å−3, versus bond lengths. (c) Plot of ∇2ρ(rcp), expressed in e Å−5, versus bond length. |
