Figure 10

The 3D spin density distribution around and within \({O}_{2}^{-}\) for (a) symmetric and (b) asymmetric dumbbell configuration. The bond in \({O}_{2}^{-}\) is also shown for clearance. Red balls: oxygens, grey balls: Al, yellow: lobed shaped 2p orbitals. The view is chosen to better show the distribution.
