nanoCHAts: Informal conversations about teaching

Submitted by Hilary Eppley / DePauw University on Wed, 04/07/2021 - 14:33

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

Comparing Homonuclear and Heteronuclear Diatomic Molecules with WebMO

Submitted by Catherine / East Tennessee State University on Wed, 11/04/2020 - 13:07

Students first learn the basics of WebMO by building and optimizing 2 small molecules. They then calculate and visualize the molecular orbitals of two diatomic molecules (N2 and BF) and observe how going from a homonuclear to heteronuclear molecule changes the shape of different molecular orbitals. 

As written this activity uses the WebMO demo server so no computational chemistry software/licences are required.

Gold carbonyl complexes

Submitted by Adam Johnson / Harvey Mudd College on Tue, 06/09/2020 - 15:06

I've been meaning to write an LO on non-classical metal carbonyl complexes for a long time. This paper describes the synthesis and characterization of a gold carbonyl prepared in superacidic media. The LO asks the students to do some relatively straightforward reduced mass calculations to predict the 13C labeled CO stretch from the unlabeled one, but then asks the students to think about /why/ the Au-CO stretch is /higher/ than that of free CO.

virtual inorganic lab experiments with data

Submitted by Adam Johnson / Harvey Mudd College on Fri, 03/20/2020 - 17:44

This collection includes new and/or updated lab experiments useful for online/distance learning. To be included in this collection, data should be provided for others to use in their new virtual laboratory courses. This collection was prepared as part of my response to the COVID-19 pandemic.

Inorganic Chemistry 2020

Submitted by Adam Johnson / Harvey Mudd College on Tue, 01/21/2020 - 17:35

Inorganic chemistry interfaces and overlaps with the other areas of chemistry. Inorganic chemists  synthesize molecules of academic and commercial interest, measure properties such as magnetism and unpaired electron spin with sophisticated instruments, study metal ion uptake in living cells, and prepare new materials like photovoltaics. Inorganic chemistry is a diverse field, and we will only be able to touch on some of the chemistry of the 118 elements that currently reside in the periodic table.

Marvin suite from ChemAxon

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.

How to Read a Journal Article: Analyzing Author Roles and Article Components

Submitted by Catherine / East Tennessee State University on Wed, 01/08/2020 - 21:09

This literature discussion uses a recently published article on solvatochromic Mo complexes to introduce students to the different components of a research article. The activity is divied into to two parts. Before class students read the paper and focus on defining terms, investigating the "meta" data of the paper, and the different sections iof the paper. In class the students work in groups to investigate the scientific content of the paper

Porphyrin UV-Vis

Submitted by Matthew Riehl / Minnesota State University, Mankato on Mon, 11/18/2019 - 16:30

The UV-vis spectra of porphyrins are among the most recognizable spectra in the chemical literature, but the electronic transitions that lead to the observed specta are not as well known.  This presentation provides an introduction to the structure and numbering of porphyrins and the origin of the bands observed in the near UV and visible region, based on the work done by Martin Gouterman beginning in the late 1950's.
