The following pages provide some 3D-models of hydrogenic atomic orbitals. In order to view these models, the Chime plugin must be installed. Please note, that the files for the contour surfaces and dotted plots are rather large and, depending on your line speed, may need some time to download. However, these are still crude representations which may not disclose the fine "inner" details of the orbitals appropriately, for high-quality images with enhanced resolution of the different orbitals see the gallery of hydrogenic orbitals and hybrid orbitals. Further informations on how these models were generated and on some background theory is also available from these pages.

• Visualizations

The plot files are not all exact 90% probability contours of the electron density ψ², but Chime renders these at a rather lower probability level. All 3D models below were calculated from the pure Cartesian wave functions of the corresponding orbitals, the plot files are not scaled relative to each other, so the size of the orbitals may not be directly compared (for orbitals of "real" atoms see the atomic orbitals derived from DFT calculations). Click on the individual images to obtain the 3D models of the orbitals, respectively; the models can be freely rotated after downloading.

The picture on the right gives an illustration on how these 3D models look like when displayed with the Chime plugin. For 3D Models of superior quality see the Jmol Models of atomic and hybrid orbitals.

Note: The f-orbitals are special in as much as two different sets of functions are commonly in use, the general and the cubic set. The latter cubic set may be appropriate for describing atoms in an environment of cubic symmetry. Both sets have three orbitals in common (nf_z³, nf_xyz, and nf_z(x²-y²) with n = 4 (4f), 5 (5f), ...).
