A Demonstration to Segue Between d to d and CT Transitions

Submitted by Marion Cass / Carleton College on Mon, 08/10/2015 - 19:21
Description

The following is a simple in-class “demonstration” that I use to segue between d to d and charge transfer transitions.  After teaching about d to d transitions and Tanabe-Sugano Diagrams, I show my students three solutions that I have put in large test tubes before class. The three solutions I place in the test tubes are:

a.  10 ml of 0.1M Co(H2O)62+

b.  10 ml of 0.1M Cu(H2O)62+

c.  10 ml of a freshly prepared 0.1 M KMnO4 solution

Peer Review - How does it work?: A literature discussion with a focus on scientific communication

Submitted by Mike Norris / University of Richmond on Thu, 07/02/2015 - 20:21
Description

This learning object is based on discussion of the literature, but it follows a paper through the peer review process.  Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots.  There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.

Analyzing a journal article for basic themes, roles of authors, and the scientific method

Submitted by Darren Achey / Kutztown University on Thu, 07/02/2015 - 15:03
Description

This literature discussion is meant to give students an understanding of both the key concept-driven and more “meta” information of a literature paper.  Students will use Jillian Dempsey’s paper, “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface-adsorbed hydrogen-evolving species,” to investigate paper authorship, how the scientific method is used in research, and how to understand the important findings of a research article.

A discussion on "Electrochemical formation of a surface-adsorbed hydrogen-evolving species"

Submitted by Kevin Hoke / Berry College on Thu, 07/02/2015 - 14:22
Description
The paper entitled “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface adsorbed hydrogen-evolving species” explores the discovery, characterization and catalytic activity of a film that deposited on the electrode while studying a nickel complex under electrocatalytic conditions.
 
This literature discussion includes several sets of questions that address different aspects of the paper, as described in the implementation notes.

Advanced Inorganic Chemistry Course Videos

Submitted by Kathryn Haas / Saint Mary's College, Notre Dame, IN on Wed, 07/01/2015 - 12:02
Description

At this website, you will find a link to the syllabus and all lecture videos for a "flipped" version of an Advanced Inorganic Chemistry Course taught at Saint Mary's College (Notre Dame, IN).  I used Shiver & Atkins for this course, and the format is based off of Dr. Franz's course at Duke.  If anyone is interested in the problem sets, I will be happy to share, although much of the material I used is from VIPEr.  

Synthesis of Aspirin- A Lewis Acid Approach

Submitted by Kathleen Field / WGU on Mon, 06/29/2015 - 21:29
Description

This is the procedure for a Fe(III) catalyzed synthesis of aspirin, an alternative to the traditionally sulfuric acid catalyzed synthesis of aspirin.  The prep compares and contrasts the Bronsted acid catalyzed esterification reaction with a Lewis acid iron (III) catalyzed pathway.  This can be used in different courses at different levels, but is it written for a general/intro level chemistry course.    

Gummies and Toothpicks Point Group Determination Activity

Submitted by Darren Achey / Kutztown University on Mon, 06/29/2015 - 15:50
Description

In this activity, students will use gummies and toothpicks to construct models of molecules that will then be analyzed for their symmetry elements, and ultimately placed into the correct point group and the models can then be consumed.

Web Resources from the 2013 Inorganic Curriculum Survey

Submitted by Barbara Reisner / James Madison University on Wed, 06/10/2015 - 10:49

 

In the 2013 Inorganic Curriculum Survey, respondents were asked about the resources they used when they teach inorganic chemistry. About 20% of respondents selected "other" and provided information about these resources. A number of people mentioned specific websites. This collection consists of the websites submitted in the survey.

Tanabe Sugano Diagram JAVA Applets

Submitted by Amanda Reig / Ursinus College on Fri, 04/24/2015 - 13:53
Description

A series of JAVA applets of Tanbe-Sugano diagrams were developed by Prof. Robert Lancashire at the University of the West Indies.  These diagrams allow students to determine deltao/B values based on ratios of peak energies without the pain of rulers and drawing lines.  There are also features that allow a person to input values and automatically calculate certain parameters.  You can also quickly find values of delta_o and B for certain complexes via a drop-down menu on some of the pages (e.g. Cr3+ complexes).
