Trends in Measured Redox Potentials and Computed Molecular Orbital Energies of Derivatized Buckminsterfullerenes

Submitted by Robert Q. Topper / Cooper Union on Tue, 06/25/2013 - 01:55
Description

In this project students are asked to reproduce published calculations of molecular orbital energies of a series of derivatized fullerenes and correlate them with published reduction and oxidation potentials obtained from cyclic voltammetry. The particular subset of the derivatives to be studied are chosen by the student and this choice is part of the learning activity. The students then carry out additional calculations using other theoretical models to see whether they improve the correlation between computed and experimental properties.

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.

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.

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.

Metal-Ligand Multiple Bonds and Frustrated Lewis Pairs

Submitted by Matt Whited / Carleton College on Wed, 10/10/2012 - 14:40
Description

This is a literature-based activity that focuses on a review I recently published as part of a thematic series on C-H activation.

The review highlights similarities between the newly discovered frustrated Lewis pairs and polarized metal-ligand multiple bonds.  There are many ways to use the review, but the attached set of questions focuses on drawing analogies among seemingly diverse types of reactivity using frontier-molecular-orbital considerations.

Atomic Orbital Display

Submitted by Flick Coleman / Wellesley College on Thu, 10/04/2012 - 12:26
Description

This is a jmol display of the atomic orbitals from 1s to 4f that can be rotated in space. They are plotted relative to the x, y, and z-axes.

The Lewis Dot Structure(s) of Nitryl Fluoride

Submitted by Sheila Smith / University of Michigan- Dearborn on Wed, 09/26/2012 - 20:43
Description

This is the In Class Activity that I use to review the concepts of Lewis Dot Structures, LDS, (connectivity, resonance, formal charges, etc.) learned in General Chemistry and to introduce new ideas of resonance contributions to the character of the molecule.  The question itself is apparently very simple, but the discussion that it produces can be quite rich and brings in both new and old ideas of LDS, providing both a good review and a good segue into advanced ideas of Lewis Dot Structures.
