Crystal Field Theory: Analysis of the Iron Sites in Gillespite

Submitted by Zachary Tonzetich / University of Texas at San Antonio on Fri, 01/03/2014 - 17:36
Description

This in-class activity explores the electronic structure and spectroscopy of the square-planar iron(II) sites in the mineral gillespite through a crystal field theory approach. This activity is designed for an advanced inorganic chemistry course where group theory and more advanced topics in ligand field theory are taught. The activity is based on the work detailed in the paper: Burn, R. G.; Clark, M. G.; Stone, A. J. Inorg.

Understanding Hypervalency Activity

Submitted by Gerard Rowe / University of South Carolina Aiken on Mon, 11/04/2013 - 10:38
Description

This activity is meant to teach students an MO theory interpretation of hypervalency that goes beyond the simple (and somewhat unsatisfying) explanation that atoms that are in the third row and below use d-orbitals for bonding in addition to s- and p-orbitals. Specifically, students will be learning how to construct MO diagrams for multicenter bonding schemes (i.e., 3c4e).  

The Iron that Keeps and Kills Us

Submitted by Katherine Franz / Duke University, Department of Chemistry on Mon, 09/16/2013 - 14:10
Description

This in-class activity requires that the students read an article in The Atlantic about an interesting (and modern) case of the plague.  The article provides a great platform to showcase the Inorganic side of broad societal themes like evolutionary biology, environmental and hereditary influences on disease, and the collaboration between biology, medicine, and history.  The article itself contains little chemistry, but can be used to guide students into learning about iron in bioinorganic chemistry.

IC Top 10 first day activity

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 09/05/2013 - 09:32
Description

I modified the Barb Reisner/Joanne Stewart/Maggie Geselbracht First Day TOC activity (https://www.ionicviper.org/class-activity/introducing-inorganic-chemist…) to take advantage of the quarterly list of Top 10 Most Read articles that IC sends out.  This is delivered to me as an email from ACS pubs and I am sure that it is available to anyone who wished to subscribe to the updates.  I have attached a pdf copy of the August 2013 update as an example.

Synthesis and Migratory-Insertion Reactivity of CpMo(CO)3(CH3): Small-Scale Organometallic Preparations Utilizing Modern Glove-Box Techniques

Submitted by Matt Whited / Carleton College on Mon, 08/26/2013 - 14:22
Description

This laboratory experiment spans three weeks and introduces advanced undergraduates to modern small-scale synthesis techniques involving an inert-atmosphere glove box.  The robust syntheses transform [CpMo(CO3]2 into the methylated CpMo(CO)3(CH3) and examine the phosphine-induced migratory insertion to form various Cp-supported Mo(II) acetyl complexes.  At each step in the synthesis, a combination of IR and multinuclear (1H, 13C, and 31P) NMR spectroscopies allow students to assess the purity of their products and

Five Slides about X-ray Photoelectron Spectroscopy (XPS)

Submitted by Sophia E. Hayes / Washington University on Fri, 06/28/2013 - 09:35
Description

This is a short presentation giving an overview of x-ray photoelectron spectroscopy (XPS), meant to be an introduction for those who are unfamiliar with the technique.

Brief introduction to local surface plasmons (LSPRs) for nanoparticle color

Submitted by Sarah K. St. Angelo / Dickinson College on Fri, 06/28/2013 - 09:30
Description

This is a very brief introduction to the origin of color in nanoparticle systems.  A link to a video is included in the slides that shows the addition of the reducing agent to the gold precursor solution.  The link is also available as a Web Resourse (below).

Cmap: Concept Mapping Tool

Submitted by Amanda Reig / Ursinus College on Thu, 06/27/2013 - 16:17
Description

Cmap Tools is a powerful free program that can be used to create concept maps.  The program works on any platform.

Thanks to Kurt Birdwhistell for posting the link to this tool to the forum a while back.

Introduction to Synchrotron Radiation

Submitted by Megan Strayer / The Pennsylvania State University on Thu, 06/27/2013 - 15:35
Description

This 5 slides about gives a basic introduction to synchrotron radiation.  Information includes how the particles are accelerated, how they travel to the individual instruments, and where synchrotrons in the USA are located.
