Course information is available through OurVLE and http://wwwchem.uwimona.edu.jm/courses. These provide the objectives and further details on the lectures, tutorials and laboratory sessions as well as examples of past examination papers.

• The basis of Crystal Field Theory.
• Crystal Field Stabilisation Energies: origin and effects on structures and thermodynamic properties,
  including the Irving-Williams series the Jahn-Teller Theorem and site preference in Spinels.
• Ligand Field Theory and evidence for the interaction of ligand orbitals with metal orbitals.
• Introduction to Absorption Spectroscopy and Magnetism. The d¹ case.

• Electronic states of partly filled quantum levels; l, m_l and s quantum numbers.
  Selection rules for electronic transitions.
  
• Splitting of the free ion energy levels in Octahedral and Tetrahedral complexes.
  D Orgel, F Orgel and Tanabe-Sugano diagrams.
  
• Spectra of aquated metal ions. The spectra of octahedral and tetrahedral Co(II) complexes.
• Factors affecting positions, intensities and shapes of absorption bands.
  

• Effect of orbital contributions arising from ground and excited states. (Magnetism PDF file)
• Deviation from the spin-only approximation.
• Experimental determination of magnetic moments.
• Interpretation of data. (Examples PDF file)

4. General properties (physical and chemical) of the 3d transition metals.

• Periodic trends in stabilities of common oxidation states.
• Contrast between first-row elements and their heavier congeners.

5. A survey of the chemistry of some of the elements Ti....Cu,
which will include the following topics:

• Occurrence, extraction, biological significance, reactions and uses
• Redox reactions, effects of pH on the simple aqua ions
• Simple oxides, halides and other simple binary compounds.
• Preparation, structures, physical properties, reactions, uses of a variety of simple coordination complexes, eg acacs, acetates, amines, etc.
  Usually, only three or four elements will be covered in detail in any year. See the individual notes covering, for example: Titanium, Vanadium, Chromium, (Cr PDF file), Manganese, Iron, (Fe PDF file), Cobalt, (Co PDF file), Nickel, (Ni PDF file), and Copper, (Cu PDF file)

• Stability and inertness, rates and mechanisms.
• Classification of inorganic reaction mechanisms. Molecularity in relation to substitution reactions.
• Square planar substitution; evidence for the 'A' mechanism. The trans- effect.
• Octahedral substitution: aquation, anation and base hydrolysis.
• Electron transfer reactions - inner/outer sphere.

• Carbonyls and other π-acceptor ligands; syntheses, structures and bonding and reactions.
• The Effective Atomic Number (EAN) rule.
• Organic ligands: alkyls, alkenes, π-allyls and aromatic ligands, including cyclopentadiene.
• A discussion of synthetic methods, structural and bonding aspects, physical properties, stabilities and important reactions.
• Catalysis and important industrial uses.
