Oxygen orbital diagram

For conjugated carbonyl compounds, such as a,) -enones, the orbital diagram would be similar, except for the recognition that the HOMO of the ground state is ij/2 of the enone system, rather than the oxygen lone-pair orbital. The excited states can sometimes be usefully represented as dipolar or diradical intermediates ... 

Caulton and Fenske began with a molecular orbital diagram for CO (see Fig. 1). The two orbitals of interest here are, of course, the Scr- and 277-orbitals. The Sa-orbital, assumed in valence-bond theory to be a carbon orbital, has in reality a small contribution from oxygen also (Sa = 0.664 2s + 0.059 2s — 0.664 2p — 0.364 2p ). One can see from the choice of...

The bond orders for ground-state molecular oxygen (dioxygen, 02), for superoxide ion (02 -), and for (HOOH) are 2, 1.5, and 1, respectively. Tabled provides molecular orbital diagrams for dioxygen ( g , Ag, and g+) and superoxide ion, which illustrates the biradical character of 62 (-02-) and the delocalized spin density of 02 - (one-half spin per oxygen). 

Before leaving the carbonates, we should note that carbon in four coordination with oxygen is observed in inorganic compounds and has been studied quantum mechanically. Tossell (1976b) calculated a molecular-orbital diagram for for a range of distances the results showed...
