Atomic orbitals: dsp3 hybrid wave function

Schematic plot of the equatorial dsp3 wave function. Blue represents negative values for the wave function and red represents positive values. The small yellow dot represents the nucleus. Click on the "Show nodal structure" button to get a clearer view of the nodal structure for this orbital.

Schematic plot of the axial dsp3 wave function. Blue represents negative values for the wave function and red represents positive values. The small yellow dot represents the nucleus. Click on the "Show nodal structure" button to get a clearer view of the nodal structure for this orbital.

In each case, the graph on the left is a plot of values along a single line drawn through the nucleus while the surface plots on the right shows values of the wave funtion ψdsp3 on a slice drawn through the nucleus.

There are five dsp3 orbitals. Three of the functions have the same shape and together form an trigonal arrangement within the overall trigonal bipyramid. These are the equatorial positions. The other two have a similar form to each other but are in the axial positions. The axial and equatorial orbitals are quite distinct from each other.

The orbitals have curved nodal surfaces separating the orbital into regions. Use the "Show nodal structure" buttons above to help see the location of the nucleus which will be revealed as a yellow dot. In each case, the larger red lobe is the "business" end and used to bind another atom. The smaller red lobe is too close to the nucleus to be used for bonding. Note that the nucleus (yellow dot) is not on the nodal surface and lies just inside the smaller lobe.
