Atomic orbitals: 3d wave functionThis page addresses the 3d_{xy}, 3d_{xz}, 3d_{yz}, and 3d_{x2y2} wave functions. See the 3d_{z2} page for information about its wave function. Schematic plot of the 3d_{xy} wave function ψ_{3dxy}. The blue zones are where the wave function has negative values and the red zones denote positive values. The graph on the left is a plot of values along a single line along the x=y line drawn through the nucleus while the surface plot on the right shows values of ψ_{3dxy} on the xy plane drawn through the nucleus. The plot above is labelled for the 3d_{xy} orbital but the form of the plots for the 3d_{xz}, 3d_{yz}, and 3d_{x2y2} orbitals is similar, differing only in orientation. See the 3d_{z2} page for comparable information about its wave function. In general, apart from the two nodal planes, dorbitals have a number of radial nodes that separate the largest, outer, component from the inner components. The number of radial nodes is related to the principal quantum number, n. In general, a nd orbital has (n  3) radial nodes, so 3dorbitals have (3  3) = 0 radial nodes. The equations for the 3d orbitals (ψ_{3d}) show that in addition to a radial dependency, there is a dependency upon direction. This is why d orbitals are not spherical. This behaviour is unlike that of the s orbitals for which the value of the wave function for a given value of r is the same no matter what direction is chosen.
