These applets are designed to help you visualise various aspects of the application of quantum mechanics to the understanding of the electronic structure of atoms and molecules.
These applets require that your browser be enabled to run Java and JavaScript (most are, by default).
The first time that you load one of the applets there may be quite a delay while the Java part and the associated files are loaded up. After this is done, things will move faster. So, be patient the first time.
These applets, and the web pages they are contained in, were developed by Stephen Elliott as part of the web-based resources for the forthcoming First-Year Chemistry, by James Keeler and Peter Wothers, OUP (2008).

Visualisation of an atomic orbital in three dimensions Ilustration of what we mean by an AO being a function of the position in space
Hydrogen atomic orbital viewer Displays 3D representations of the hydrogen AOs, which can be rotated in real time
Formation of bonding and antibonding MOs Shows how the form of the bonding and antibonding MOs varies with the distance between the interacting AOs
Effect of energy match on the form of the MOs Shows how the form of the MOs (their energies and wavefunctions) varies as the energy of the AOs is altered
