Reaction Report

Submitted by RSwails / Lafayette College on Mon, 06/27/2016 - 15:24
Description

Students are asked to choose a type of reaction from a set list (included), determine appropriate starting materials and the resulting product and present the reaction as though they accomplished it in the laboratory setting (5 min oral presentation with a 1 page paper).  I asked the students to perform both a rough draft presentation (to me) and final draft presentation (to all students in laboratory).

Uses for Character Tables: IR and Raman Spectroscopy

Submitted by Kristy L. Mardis / Chicago State University on Mon, 06/27/2016 - 10:11
Description

A guided inquiry activity where students use group theory and character tables to practice determining reducible representations for all atoms and the individual bonds (like CO stretches).  The students then reduce the representation, determine which are vibrational modes, and then determine which are IR active using the character table.  For the second portion, they practice using this approach to differentiate between two metal isomers.

Visualizing solid state structures using CrystalMaker generated COLLADA files

Submitted by Barbara Reisner / James Madison University on Wed, 06/22/2016 - 16:59
Description

Although I’m a solid state chemist, I still find it difficult to teach the visualization of solid state structures. I’m interested in any tool that helps my students visualize solids. My experience is that the more representations students can master, the more likely they are to find one that helps them understand solid state structures.

I’ve used many tools. These include

A model for every student: Visualizing solid state structures

Submitted by Barbara Reisner / James Madison University on Tue, 06/21/2016 - 13:11
Description

We do not cover extended solids (solid state materials) in our general chemistry program. With the exception of students who have taken a course in materials science, Inorganic Chemistry I is the first time our students have encountered solid state structure. Although they have built some visualization skills by working with molecules and symmetry, they do not have robust 3D visualization abilities and have trouble using the language of solid state chemistry (unit cells, packing, filling holes, coordination number, etc…) in the context of structure.

Chapter 2--Stanley Organometallics

Submitted by George Stanley / Louisiana State University on Mon, 06/20/2016 - 12:57
Description

Chapter 2 from George Stanley's organometallics course, Lewis Base ligands

 

this chapter covers halides, oxygen and nitrogen donor ligands

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I share these with students after the class, but not before.

Everyone is more than welcome to edit the materials to suit their own uses, and I would appreciate being notified of any mistakes that are found.


George Stanley Organometallics

Submitted by Adam Johnson / Harvey Mudd College on Fri, 06/10/2016 - 14:53

This is an LO for the collection of organometallics LOs by George Stanley. Adam Johnson is curating the material that was written by George.

For many years, George hosted his organometallics lecture notes, powerpoint slides, and handouts, on his personal website at LSU. He always wanted that material available to the public. Recently, they moved to a CMS and that material is no longer available. Adam is working with George to get the 2016-2017 version of his materials up on VIPEr for everyone to use.

The lecture notes are freely available to all.

This chapter is an overview of the field, with an emphasis on electron counting

Historical overview of Evans method

Submitted by Adam Johnson / Harvey Mudd College on Wed, 06/08/2016 - 20:08
Description

This LO grew out of my interest in understanding (deeply) the machinery behind the Evans method calculations. I did these calculations as a grad student to characterize my compounds, and I teach it in both my lecture and lab. Currently I use the metal acac synthesis lab to motivate the problem.

magnetism by Evans method

Submitted by Adam Johnson / Harvey Mudd College on Tue, 05/31/2016 - 16:27
Description

After I teach my students about magnetism and magnetic properties in coordination compounds, I spend a day showing how the data is collected and analyzed. I teach them about the Gouy balance, the Evans method of determining magnetism by NMR, and SQUID magnetometry. I also show them real data that I collected as an undergraduate or graduate student, and have them interpret and analyze it.

The only experiment that we can do locally is the Evans method, so I spend more time on this technique. We use the method during the metal acac laboratory.
