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.

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.

Shapes of d Orbitals  William F. Coleman
Shapes of d Orbitals shows the d orbitals in an axis set. Running the mouse over an orbital reveals the "name" of that orbital. This is good practice for helping students link the name of an orbital to the orientation.Shapes of d Orbitals has a link to D Orbitals in an Octahedral Ligand Field. Here the user may click on the name of any one of the d orbitals to obtain a larger 3-dimensional image. The images are rotatable and scalable. Orbital phase is shown by the different colors.

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.
