Valence-bond Theory

It is very difficult to represent valence-bond wavefunctions because they refer to two electrons simultaneously. However, this illustration is an attempt. The atomic orbital for electron 1 is represented by the black contours, and that of electron 2 is represented by the green contours. The top illustration represents A(1)B(2), and the middle illustration represents the contribution A(2)B(1). When the two contributions are superimposed, there is interference between the black contributions and between the green contributions, resulting in an enhanced (two-electron) density in the internuclear region.
