Molecular orbitals (MO) are constructed from atomic orbitals. In O2 and F2, there is a crossover of the sigma and the pi ortbials: the relative energies of the sigma orbitals drop below that of the pi orbitals'. Information from the MO diagram justify O2's stability and show that it's bonding order is 2. The LUMO (lowest unoccupied molecular orbital) and HOMO (highest occupied molecular orbital) of difluoride's MO diagram help explain why the molecule is very stable - the diagram also tells us that the bond order is 1.
Types of Interaction
The formation of F2 and O2 involves 2s-2s and 2p-2p orbital interactions. S-orbitals are independent of the angular part of the wavefunction; so, they, as well as the 2pz orbital, show spherically symmetry about the nucleus. The in-phase and out-of-phase combinations of the orbitals lead to the organization of the sigma g and sigma star u labels. However, the 2px and 2py atomic orbitals combine to form pi and pi-star molecular orbitals because they are dependent on the angular part of the wavefunction.
