Oxygen orbital potential energies

FIGURE 5-23 Orbital Potential Energies of Carbon and Oxygen. 

Fig. 2-1. Atomic orbital levels of oxygen occupied by electrons c = electron energy V(r) = potential energy of atomic oxygen nucleus r = distance finm atomic nucleus.

The molecular orbitals from which the ionization takes place are assigned. The first one (4b) 1 is due to the out ofphase combination of oxygen lone pairs while the second one (5a) 1 is due to the in phase combination of the lone pairs and the (7 (O-O) bond. Detailed investigations of the potential energy surfaces of the... 

The 2s and 2p orbitals of carbon, therefore, have two possible sets of group orbitals with which they may interact. In other words, all four interactions in Figures 5-21 and 5-22 occur, and all four are symmetry allowed. It is then necessary to estimate which interactions can be expected to be the strongest from the potential energies of the 2s and 2p orbitals of carbon and oxygen given in Figure 5-23.
