Teaching Computational Chemistry

Submitted by Joanne Stewart / Hope College on Thu, 05/23/2019 - 14:10

This is a series of in-class exercises used to teach computational chemistry. The exercises have been updated and adapted, with permission, from the Shodor CCCE exercises (http://www.computationalscience.org/ccce). The directions provided in the student handouts use the WebMO interface for drawing structures and visualizing results. WebMO is a free web-based interface to computational chemistry packages (www.webmo.net).

CompChem 03: Choice of Theoretical Method

Submitted by Joanne Stewart / Hope College on Mon, 05/20/2019 - 10:54
Description

This is the third in a series of exercises used to teach computational chemistry. It has been adapted, with permission, from a Shodor CCCE exercise (http://www.computationalscience.org/ccce). It uses the WebMO interface for drawing structures and visualizing results. WebMO is a free web-based interface to computational chemistry packages (www.webmo.net).

In the exercise, students compare the computational results (structures and energies) for different theoretical methods and basis sets.

CompChem 02: Introduction to WebMO

Submitted by Joanne Stewart / Hope College on Mon, 05/20/2019 - 10:11
Description

This is the second in a series of exercises used to teach computational chemistry. It has been adapted, with permission, from a Shodor CCCE exercise (http://www.computationalscience.org/ccce).

It was tested on WebMO Version 18 but should work with minimal modification on earlier versions. WebMO is a free web-based interface to computational chemistry packages (www.webmo.net).

5-ish Slides About Bridging Hydrides and the [Cr(CO)5HCr(CO)5] anion

Submitted by Kyle Grice / DePaul University on Thu, 01/31/2019 - 13:52
Description

This set of slides was made for my Organometallics class based on questions about bridging hydrides and specifically the chromium molecule. I decided to make these slides to answer the questions, and do a DFT calc to show the MO's involved in bonding of the hydride. 

 

Interpreting Reaction Profile Energy Diagrams: Experiment vs. Computation

Submitted by Douglas A. Vander Griend / Calvin College on Sat, 06/23/2018 - 10:56
Description

The associated paper by Lehnert et al. uses DFT to investigate the reaction mechanism whereby a flavodiiron nitric oxide reductase mimic reduces two NO molecules to N2O. While being a rather long and technical paper, it does include several figures that highlight the reaction profile of the 4-step reaction. This LO is designed to help students learn how to recognize and interpret such diagrams, based on free energy in this case. Furthermore, using a simple form of the Arrhenius equation (eq.
