Character Tables and One Application of Symmetry

    Chemistry 107 Lecture 04

• Explanation: (a) In the first 12 minutes, vibrational selection rules are presented for the MCl3(CO)3 compounds. (b) Molecular Orbital Theory requires energy, symmetry, and overlap. Linear combinations of atomic orbital method (LCAO) method is introduced along with the first three "Basic Rules of MO Theory." RULE 1: The number of MOs out equals the number of AOs in. RULE 2: If AOs are degenerate, the interaction is proportional to the overlap interval, S. RULE 3: Orbitals must have the same symmetry to have non-zero overlap. Overlap and bond type is presented.
