Atomic orbitals: sp3 hybrid wave function

Schematic plot of the sp3 wave function. Blue represents negative values for the wave function and red represents positive values. Click on the "Show nodal structure" button to get a clearer view of the nodal structure for this orbital.

The graph on the left is a plot of values along a single line drawn through the nucleus while the surface plot on the right shows values of the wave funtion ψsp3 on a slice drawn through the nucleus.

There are four sp3 orbitals. These functions have the same shape but are related to each other by a 109.5° rotation.

The orbital has a curved nodal surface separating the orbital into two regions. Use the "Show nodal structure" button above to help see the location of the nucleus which will be revealed as a yellow dot. The larger lobe is the "business" end and used to bind another atom. The smaller lobe is too close to the nucleus to be used for bonding. Note that the nucleus is not on the nodal surface and lies just inside the smaller lobe.
