Amalgams molecular orbitals

Atomic structure based on the theory of wave mechanics is described in most modem textbooks on chemistry and there is also a brief account given by Coates (Jf.S.D.C., 1967,83,96), but a short reference to molecular orbitals may not be out of place. Molecular orbitals are formed by the amalgamation of those atomic orbitals where a high degree of overlap is possible, and a few extremely simple examples are shown in Fig. 12.2.
