Figure 2
Δρ maps drawn with positive contours as solid lines, negative contours as dashed lines and an increment interval of 0.4 e Å−3 [σ(Δρ) = 0.25 e Å−3] for (a) the (010) plane through Ti1, (b) the (100) plane through Ti2, (c) the (010) plane through Rb1 and (d) the plane through As1, O3 and O4. The borders are 3.5 Å for (a), (b) and (d), and 2.5 Å for (c). |
