Sigma molecular orbitalsThe QuickTime movies below supplement the discussion in the text on pages 582 through 585, especially Figures 16.1 and 16.2. In each movie, you will see the evolution of the bonding and antibonding sigma molecular orbitals for H2+. The black dot on the energy curves (compare Figure 16.2) follows the internuclear separation R (expressed as a multiple of the Bohr radius). The MOs are shown in two ways: as a density plot and as a 3D view. Note how the bonding MO builds the wavefunction in the bonding region while the antibonding MO produces a node that excludes electron density from the bonding region.
