Jahn-Teller effect, theory and examples

Submitted by Adam Johnson / Harvey Mudd College on Thu, 08/06/2020 - 18:44
Description

At a recent SLiThEr workshop, a request was put out for an introduction to the Jahn-Teller effect. I had already prepared several slides showcasing single crystal X-ray data for my class this spring so I put this together with some additional examples from my lab and the literature.  Single crystal XRD data is presented to support the claims.

Ferrocene acylation - The Covid-19 Version

Submitted by Chip Nataro / Lafayette College on Sat, 03/21/2020 - 12:56
Description

This is the classic Chromatography of Ferrocene Derivatives experiment from "Synthesis and Technique in Inorganic Chemistry" 3rd Ed. (1986 pp 157-168) by R. J. Angelici.

Job's Method - The Covid-19 Version
Description

This is the classic Job's Method experiment from "Synthesis and Technique in Inorganic Chemistry" 2nd Ed. (1977 or 1986 pp 108-114) by R. J. Angelici. There are slight changes from the experiment published in the book but they just include running solutions with ethylenediamine mole fractions of 0.67 and 0.75, so details will not be provided. What is provided are a series of pictures and videos showing the experiment being performed. Also included are the raw files of the absorbance spectra in EXCEL.

Solid State Structures tutorial

Submitted by Terrie Salupo-Bryant / Manchester University on Sat, 03/14/2020 - 12:19
Description

This tutorial will introduce students to some of the three-dimensional crystal structures exhibited by ionic and metallic solids.  They will examine the simple cubic, body-centered cubic, face-centered cubic, and the hexagonal closest-packed systems.  To facilitate visualization of the structures at the atomic level, they will use the Crystal Explorer website at Purdue University.

iPad Screen Recording

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 03/12/2020 - 10:46
Description

Many faculty and students now have iPads and Apple Pencils for use in their classes. At Merrimack, we have a 1:1 iPad program (called Mobile Merrimack) in which all students and faculty are provided an iPad and students are also given an Apple Pencil and a keyboard.

ChemCrafter
Description

ChemCrafter, from the Science History Institute (formerly the Chemical Heritage Foundation), is a free iPad app that mimics a classic chemistry set. It is set up as a game, with three sections: reactions with water, reactions with acid, and salts. The app shows the progress of the reaction (smoke, color change, etc.) when two elements are mixed in a reaction vessel, and also gives the change in enthalpy of the reaction.

Marvin suite from ChemAxon

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/09/2020 - 12:10
Description

It is important for students to be able to effectively communicate the results of their scientific work. This does not only inlcude written and oral communication, but the creation of appropriate representations of the complexes they have investigated. It is crucial that students learn how to draw molecules using electronic structure drawing programs, but site licenses for structure drawing programs can be prohibitive for some institutions.

An improved method for drawing the bonding MO for dihydrogen

Submitted by Adam Johnson / Harvey Mudd College on Sun, 06/09/2019 - 14:42
Description
Most of us have probably been there. Discussing homonuclear diatomic MO diagrams and on the first day you want to put up the sigma bonding molecular orbital for H2. If you teach it like me, you emphasize the LCAO-MO approach, so you draw a hydrogen atom with its 1s orbital interacting with a hydrogen atom with its 1s orbital...and then you notice giggling from the less mature audience members. My technique will help to prevent this from happening. The technique is in the "faculty only" files section.
