41. The lowest energy 1s molecular orbitals are uniformly filled in all three and are omitted for simplicity. 42. Similarly, the ? and ? * molecular orbitals of the product are characterized by their symmetry. 43. Cotton and Harris formulated a molecular orbital rationale for the bonding that explicitly indicated a quadruple bond. 44. Zigzag edges provide the edge localized state with non-bonding molecular orbitals near the Fermi energy. 45. Molecular orbitals of Td molecules can be determined using reducible representations, SALCs and projection operator techniques.46. Computer modeling of molecular orbital theory indicates that this bonding involves only s-and p-orbitals. 47. The expression ( linear expansion ) for the " i " th molecular orbital would be: 48. This had long been a point of contention and confusion in describing these molecules using molecular orbital theory. 49. Hybridisation theory is an integral part of organic chemistry and in general discussed together with molecular orbital theory. 50. Shown are three electronic configurations of the molecular orbitals ( MOs ) of molecular oxygen, O 2.
