Quantum States of Atoms and Molecules  Theresa Julia Zielinski, Erica Harvey, Robert Sweeney, David M. Hanson
Quantum States of Atoms and Molecules is an introduction to quantum mechanics as it relates to spectroscopy, the electronic structure of atoms and molecules, and molecular properties. A digital, living textbook, it provides opportunities not found in conventional textbooks opportunities that allow students to develop skills in information processing, critical thinking or analytical reasoning, and problem solving that are so important for success.

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.

Solving the Hydrogen Atom  Todd M. Hamilton
After practicing with the particle-in-a-box problem, students solve the H atom symbolically using the derivatives feature in MathCad. The result is an expression for the energy levels of the hydrogen atom. Students will also prove that the radial part of the wavefunction is normalized and explore the concept of an orbital.

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.

Atomic Spectra  William F. Coleman
In this Flash animation the user can view the atomic emission spectra (400-700nm) of eight different elements. A dragable marker allows the user to approximate the wavelength of the various spectral lines. The effect of resolution can be examined in the sodium spectrum in the region 550-600nm.

Bohr Hydrogen Atom Emission Series  William F. Coleman
In this Excel spreadsheet students use interactive arrows to explore various series in the hydrogen spectrum. The arrows change the final quantum state of the series. A second tab opens a sheet that allows exploration of the spectra of other one-electron species, by varying the nuclear charge. The nuclear charge is entered and the arrows again control the final state of the spectral series.

Photoelectric Effect  William F. Coleman
This is a series of simulations of aspects of the photoelectric effect. There is an animation of the experiment with four choices of incident radiation - low and high intensity "red", to represent low energy light and low and high intensity "blue" to represent higher energy light. Electron production is animated and there is an ammeter to simulate current flow. Additional simulations show the effect of light frequency and intensity. There is a link to a spreadsheet that allows students to choose a sample from among five metals. The spreadsheet includes several questions to be answered after working through the materials.

Restricted Hartree-Fock SCF Calculations Using Microsoft Excel  Mark A. Freitag, Cortney A. Boots, Taylor R. Page
Courses in computational chemistry are increasingly common at the undergraduate level. Excellent user-friendly programs, which make the execution of ab initio calculations quite simple, are available. However, there is a danger that the underlying SCF procedure (usually coupled with contracted Gaussian atomic orbital basis sets) can become a ?black box? for the student. This Microsoft Excel spreadsheet contains all the essential elements of far more complicated ab initio calculations, but on the simplest possible molecular system.

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.
