This is an In class exercise on the subject of Ligand Field theory. It reviews nomenclature and introduces ideas of ligand field splitting and spin in transition metal complexes. It includes both a worksheet for classroom use, a worksheet key which includes some information not on the student worksheet .
This book called to me given my fascination with both origami and molecular model kits. While not a textbook in the true sense, the content of the book is pertinent to topics of molecular structure and symmetry and is therefore potentially valuable in both general and inorganic chemistry courses. In addition to the plans for constructing all the models (~125), there is a small amount of background information. Granted, many of these models could more easily be made using traditional model kits, but I had fun building them from paper.
This laboratory exercise was developed to compliment several weeks of freshmen or sophomore level quantum chemistry lecture material at our institution. The students meet in a computer lab on campus and use the software package known as GaussView.
Molecular models and selected molecular orbital surfaces and slices were calculated with Spartan for HF, LiH, CO2, XeF2, and BF3, and the results were used by students in an in-class activity (covering several class sessions) to answer a series of questions.

A set of Flash-based, interactive tools for students to construct Lewis structures for electron deficient, octet rule obeying and hypervalent MLx molecules and ions (x = 2 - 6).
The user chooses the number of electrons and bond type (single, double or triple) and is steered towards the correct stucture.
For cases where resonance structures are possible, the user must construct each form to complete the puzzle.
This in-class activity was used on the first day of Advanced Inorganic Chemistry in lieu of lecture to review symmetry operations and point groups in small molecules. The learning object was adapted to a small group discussion format from a fundamental quiz posted by Barbara Reisner (James Madison University) and a problem set question posted by Adam Johnson (Harvey Mudd College).

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
