Interactive Pi Bonding Effects  William F. Coleman
This application demonstrates the effect of pi bonding on the one-electron ligand field splitting in an octahedral. By clicking on the appropriate buttons students can see how D changes when you move from ligands with no pi bonding capability to pi donor and pi acceptor ligands.

Photosystem II Oxygen-Evolving Complex  William F. Coleman
Both introductory texts and texts for upper-level inorganic chemistry courses are shifting the emphasis in their coverage of transition metal chemistry from classical Werner complexes to those that exhibit some form of catalytic activity. This is of particular importance to bioinorganic chemistry, a now mature area of the science, but one that is still underrepresented in the undergraduate curriculum. Derrick L. Howard, Arthur D. Tinoco, Gary W. Brudvig, John S. Vrettos, and Bertha Connie Allen address this issue in their paper Catalytic Oxygen Evolution by a Bioinorganic Model of the Photosystem II Oxygen-Evolving Complex by a dimanganese complex that is proposed as a model for the four-manganese center in Photosystem II. The featured molecules for May are the model compound in the proposed mechanism for oxygen production.

Interactive Molecular Orbital Diagrams  William F. Coleman
Here is an application for constructing the molecular orbital electron configurations of heteronuclear diatomic molecules. Energy level diagrams are given for the two different cases encountered in heteronuclear diatomics of the first short period (Li2 - Ne2). This is a useful tool for having students explore questions of bond order, magnetic properties and numbers of unpaired electrons.

Heteronuclear Diatomic Molecular Orbital Formation  William F. Coleman
Here is a set of movies that demonstrates heteronuclear diatomic molecular orbital formation. The orbitals start at a distance where there is little or no interatomic interaction and move to the appropriate bond distance. Orbital phase is shown by the different colors.

Interactive Spreadsheets  William F. Coleman
Interactive Excel spreadsheets display hard-to-understand concepts in statistics, quantum mechanics, physics, and more. Parameters are adjusted by clicking on easy-to-use buttons or by using numeric input boxes. Graphs, tables, and/or figures are then created reflecting the change in parameters.
