Figure 6
Difference maps for SP8 data of (a) static electron density (contour ±0.01 e A−3) and (b) negative Laplacian (contour values are in geometric order, starting from ±0.1 e A−5 with increments of 2 e A−5) exposing both the effects of relativity (REL) and electron correlation (ECORR). (c) 2D and 3D dynamic electron density in the plane of P—Au—C atoms exposing the effect of anharmonicity (ANH). Values of the positive and negative difference densities are denoted by blue solid and red dashed lines, respectively.
