Teaching Tanabe-Sugano Diagrams

Submitted by Sheila Smith / University of Michigan- Dearborn on Tue, 05/03/2011 - 11:12
Description

For years, I spent 2-3 days a semester working through Tanabe-Sugano diagrams, their development from terms, their evolution from Orgel diagrams, their analysis to give transition energies (the old ruler- trial and error analysis) and nephalauxetic parameters.  Recently, colleagues in VIPEr convinced me that my time in class could be better spent, but I am not willing to completely give up on Tanabe-Sugano.

19F NMR In-class exercise

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 04/04/2011 - 12:27
Description

This is an in class activity to introduce the topic of multinuclear NMR, which is not covered (beyond 13C) in our sophomore level organic course. It is designed to walk the students through the process of predicting NMR spectra, as they learned in sophomore organic chemistry, but for a different I=1/2 nucleus, in this case 19F, which is I=1/2 and 100% abundant. 

 

Synthesis and Molecular Modeling of Sodium Tetrathionate

Submitted by Kim Lance / Ohio Wesleyan University on Sat, 07/17/2010 - 12:01
Description
This experiment is a computational supplement to synthesis of sodium tetrathionate described in "Macroscale Inorganic Chemistry:  A Comprehensive Laboratory Experience".*  Students will synthesize one sulfur oxyanion (tetrathionate), optimize and compute IR spectra for their synthesized product.   In addition, students will predict (using symmetry arguments) and then compute the IR vibrational modes for six additional sulfur oxyanions.  A comparison of theoretical (IR spectra),

In-Class Review of Symmetry Operations and Point Groups

Submitted by Maggie Geselbracht / Reed College on Wed, 08/19/2009 - 14:50
Description

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).

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

 

IR Spectroscopy of Rhodium Carbonyl Clusters

Submitted by Maggie Geselbracht / Reed College on Tue, 04/07/2009 - 02:07
Description
The structures of neutral rhodium carbonyl clusters containing two, four, and six rhodium atoms have been known for some time.  In a recent paper (J. Am. Chem.

Symmetry Resources at Otterbein University

Submitted by Dean Johnston / Otterbein University on Sat, 03/28/2009 - 23:42
Description

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.

Inorganic Challenges

Submitted by Patrick Holland / Yale University on Tue, 03/10/2009 - 15:39
Description

The Interactive Inorganic Challenge Forum is a resource for inorganic chemistry teachers who want to incorporate team learning questions (“Challenges”) into an upper level undergraduate inorganic course. Through this site, teachers can exchange their ideas with others who have used inorganic chemistry Challenges. As a result, students benefit from field-tested group questions.

House: Inorganic Chemistry

Submitted by Adam Johnson / Harvey Mudd College on Mon, 01/12/2009 - 15:35
Description

House (Inorganic chemistry):  The book is divided into 5 parts:  first, an introductory section on atomic structure, symmetry, and bonding; second, ionic bonding and solids; third, acids, bases and nonaqueous solvents; fourth, descriptive chemistry; and fifth, coordination chemistry.  The first three sections are short, 2-4 chapters each, while the descriptive section (five chapters) and coordination chemistry section (seven chapters covering ligand field theory, spectroscopy, synthesis and reaction chemistry, organometallics, and bioinorganic chemistry.) are longer.  Each chapter includes

Point Group Symmetry Game

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 09:59
Description

This is a game that gets students interested in point group symmetry, and helps them to see the symmetry in everyday objects. It is a competition in which the groups try to bring in the hardest object to assign. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.
