WS 2006/2007 (16.10.2006 - 9.02.2007)

Part I: Transition metal complexes and clusters

1. Crystal field theory (CFT) vs. Angular Overlap Model (AOM) • physical basis of CF theory • basic group theory concepts • elementary Hückel theory • spectrochemical series • / bonding influence on energy splittings

2. MO theoretical analysis of transition metal complexes • effective atomic number (EAN) rule • MO diagram construction rules

3. Is the Jahn-Teller Effect as simple as it seems? • first order & second order J-T effect • pseudo J-T distortion • elementary second order perturbation theory

4. The electronic structure of hypervalent compounds and electron deficient clusters • isolobal relationship • Wade rules • skeletal bonding • delocalized valence bonding

Part II: Ceramics and Hybrids

5. How to derive the orbital structure of solids from that of large molecules • periodicity & Bloch functions – a group theoretical approach • LCAO theory • elementary band theory • band structure diagrams • density of states • effective mass concept • electronic conductivity • band structure & spectroscopy

6. The electronic structure of ceramics and hybrids • band structure analysis of 1D, 2D & 3D framework compounds
