1 Lecture 16 Molecular Orbital Theory 8.12 Lecture 16, Knowledge and Skills • Form molecular orbitals from atomic orbitals bonding and nonbonding molecular orbitals ± and ² molecular orbitals • Molecular orbital energy diagram • Molecular electron configuration • Predict physical properties of diatomic molecules: bond order; magnetism; relative bond lengths Molecular Orbitals, Basic Aspects Atomic orbitals provide information about the location and energy of electrons within atoms. Atomic orbitals can be calculated by means of quantum mechanics. You are familiar with the results of these calculations: s, p, d, f … orbitals. Molecular orbitals could be obtained in a similar fashion by calculating the wavefunctions of electrons moving in the field of two or more nuclei. Unfortunately, this procedure would be very difficult. It is easier to construct molecular orbitals by combining known atomic orbitals. This procedure is justified since in molecules most of the electron electron density is still found near the nuclei of the atoms.
