Flash based tools to help with the construction of MO diagrams:

• "energy levels" shows how the form of the bonding and antibonding orbitals, the bond order and atomic charges vary in a diatomic molecule with the electronegativity of the two atoms involved
• "Molecular orbital diagram maker" shows how a complex MO diagram can be made by a drag and drop approach using symmetry adapted components

The resources contained within this web site are designed to help students learn concepts of molecular symmetry and to help faculty teach concepts of molecular symmetry.

This spreadsheet allows students to build complexes of a variety of geometries and to then use the angular overlap model to explore d-orbital energies when interacting with ligands whose esigma and epi energies can be varied.

I developed this Jmol page to help my students see the relationship(s) between the ligands and metal d-orbitals in a number of different geometries.  Since the images are all rotatable, students who have difficulty looking at flat images and drawing appropriate conclusions have that barrier reduced or eliminated.  I have now used the application twice - this past fall in the second semester of introductory chemistry and a few weeks ago when I began ligand field theory in my inorganic course.  In both classes I received favorable comments.  A number of students in the inorganic course, who h

Over the years I have developed a number of interactive tools that I use in my classes. This is a tool that seems appropriate for VIPEr. Comments are always appreciated, and I am always interested in developing new tools if there is something you might find useful.

This tool allows you to look at how molecular orbitals change as the difference in electronegativities of the parent atomic orbitals increases.

This web site contains a number of interactive spreadsheets, most of which are applicable to inorganic chemistry (or a physical chemistry class that uses inorganic examples).  Here's the list of the most relevant for most inorganic classes:

ABC kinetics - interactively plot concentration versus reaction extent for A, B and C in A -> B -> C by varying k values
