Topic 1.4. Representation of Electron Density by the Laplacian Function 

Electron distribution in molecules can be usefully represented by the Laplacian of the electron density. The Laplacian is defined by the equation 

These diagrams can help to visualize the electron density associated with these prototypical molecules. We see that most electron density is closely associated with
