Band Structures, Electronic and Optical Properties of Metals, Semiconductors, and Insulators

Submitted by Maggie Geselbracht / Reed College on Tue, 06/25/2013 - 00:32

I created this Collection of Learning Objects (LOs) at the IONiC VIPEr TUES 2013 Workshop: Solid State Materials for Alternative Energy Needs held at Penn State University.  The overall theme of the Collection is electronic and optical properties of metals, semiconductors, and insulators.  Most of the learning objects either require knowledge of or explicitly refer to band structures, either at a basic level or a more advanced level.  Some LOs also deal with extended structures, un

Symmetry, Group Theory, and Computational Chemistry

Submitted by Joanne Stewart / Hope College on Mon, 06/24/2013 - 22:46

These Learning Objects were used in an advanced undergraduate chemistry course that used computational chemistry as an integrative tool to help students deepen their understanding of structure, bonding, and reactivity and practice their integrative expertise by addressing complex problems in the literature and in their own research.

Lithium Diazenide Surprise!

Submitted by Maggie Geselbracht / Reed College on Fri, 05/31/2013 - 23:00
Description

Students in a sophomore-level inorganic chemistry course were asked to read the paper “High-Pressure Synthesis and Characterization of the Alkali Diazenide Li2N2” (Angew. Chem. Int. Ed. 2012, 51, 1873-1875. DOI: 10.1002/anie.201108252) in preparation for a class discussion.  For many students, this was a first exposure to reading the primary literature. 

A DFT Study of Metal Pentacarbonyls

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Thu, 05/09/2013 - 16:57
Description

Metal carbonyls are the most widely studied organometallic complexes.  This exercise uses Gaussian with the GaussView interface to investigate the role of the metal centers on backbonding to the CO ligand. Density Functional Theory (DFT) methods were used to evaluate two classic metal pentacarbonyls, namely Fe(CO)5 and Ru(CO)5.

 

Inorganic Chemistry Forums

Submitted by Adam Johnson / Harvey Mudd College on Fri, 04/26/2013 - 12:55
Description

Beginning with Volume 43, Issue 25, Inorganic Chemistry began publishing Forums.

Inorganic Chemistry Forums consist of a set of thematically linked papers from leading scientists on a multidisciplinary topic of growing interest. Papers present overviews, research perspectives and original research reports on the Forum theme and are highlighted on the cover of the journal issue in which they appear.

Description

This website is a free and comprehensive resource that is a collection of open college courses that spans videos, audio lectures, and notes given by professors at a variety of universities. The website is designed to be friendly and designed to be easily accessed on any mobile device.

So Much Nitrogen: Maggie's Explosive Main Group Compounds

Submitted by W. Stephen McNeil / University of British Columbia Okanagan on Thu, 03/21/2013 - 00:47

Maggie Geselbracht has a great fondness for compounds with too many nitrogen atoms next to each other.  This is a collection of problem sets and class activites based on the structure, bonding, and spectroscopy of a number of such compounds, drawn from the recent literature.

Voices of Inorganic Chemistry

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Sun, 01/27/2013 - 17:08
Description

This learning object focuses on the new video series, “Voices in Inorganic Chemistry,” established to commemorate the 50th anniversary of the American Chemical Society journal, Inorganic Chemistry. The are currently 12 videos celebrating pioneers in the field of inorganic chemistry.  This activity consists of two components, namely the students watching one interview and writing an essay about their chosen inorganic chemist.

(mu-NO)2[CoCp]2 is not paramagnetic

Submitted by Joanne Stewart / Hope College on Fri, 10/26/2012 - 02:05
Description

In this paper by Andersen and Berg (J. Am. Chem. Soc.1988110 (14), pp 4849–4850) the authors present magnetic measurements that refute the calculated ground state of an organometallic cobalt nitrosyl dimer. Students will learn about two physical techniques for measuring magnetism and will learn how magnetic measurements can be used to indicate paramagnetism versus diamagnetism.

Alkyne Semihydrogenation with Niobium(II) Imido Complexes: Exploring An Unconventional Hydrogenation Mechanism

Submitted by Matt Whited / Carleton College on Thu, 08/09/2012 - 11:30
Description

This is a literature discussion based on an interesting Bergman/Arnold paper utilizing d2 niobium imido complexes for the semihydrogenation of arylalkynes to Z-alkenes.  The mechanism is quite unusual, and I found it to be an interesting paper to discuss after we had talked about the classical hydrogenation mechanisms (typically observed for late transition metals).  The students should come into the discussion understanding fundamental reaction mechanisms (including σ-bond metathesis), and it's helpful if they are somewhat familiar with mono- and dihydride mech
