A discussion on "Electrochemical formation of a surface-adsorbed hydrogen-evolving species"

Submitted by Kevin Hoke / Berry College on Thu, 07/02/2015 - 14:22
Description
The paper entitled “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface adsorbed hydrogen-evolving species” explores the discovery, characterization and catalytic activity of a film that deposited on the electrode while studying a nickel complex under electrocatalytic conditions.
 
This literature discussion includes several sets of questions that address different aspects of the paper, as described in the implementation notes.

Vibrational Modes and IR Spectra using Character Tables

Submitted by Karen McFarlane Holman / Willamette University on Tue, 06/30/2015 - 15:35
Description

In this activity, students in my upper-level Inorganic course are given two possible structures of sulfur dioxide, and based on an assessment of given vibrational modes, they determine which of the modes are IR active by two methods: (1) the “Intro Chem” method (determing whether the dipole moment changes for a particular vibrational mode) and (2) using character tables. They compare their assessment to experimental IR absorption peaks, and the students decide which structure is valid. For those of you who teach Raman spectroscopy, it could be included in this LO as well. 

Vibrational Modes and IR Spectra for Intro Chem

Submitted by Karen McFarlane Holman / Willamette University on Mon, 06/29/2015 - 15:14
Description

In this activity, Introductory Chemistry students are given two possible structures of sulfur dioxide, and based on an assessment of given vibrational modes, they determine which of the modes are IR active (and thus, whether the molecule is a greenhouse gas).  They compare their assessment to experimental IR absorption peaks, and the students decide which structure is valid.

Introduction to Miller Indices

Submitted by Vanessa / Albion College on Mon, 06/29/2015 - 14:22
Description

Towards the end of the semester, when we were starting to read more of the primary literature, I realized that the Miller Indices were present in most of the papers that I wanted to discuss. However, I couldn't find any good resources in textbooks that would help to explain what these were. I found this online resource through the University of Cambridge that is engaging, interactive and concise.

Web Resources from the 2013 Inorganic Curriculum Survey

Submitted by Barbara Reisner / James Madison University on Wed, 06/10/2015 - 10:49

 

In the 2013 Inorganic Curriculum Survey, respondents were asked about the resources they used when they teach inorganic chemistry. About 20% of respondents selected "other" and provided information about these resources. A number of people mentioned specific websites. This collection consists of the websites submitted in the survey.

Introduction to Mercury

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/22/2015 - 20:57
Description

In this exercise, students are introduced to Mercury, a program for visualizing and analyzing crystal structure data.  Students are guided through opening the program for the first time and viewing a structure from the Teaching Subset, a selection of structures from the Cambridge Crystallographic Database (CSD). Activites include changing the representation of the complex, moving the structure around the window, accessing information about the structure, and measuring bond lengths and angles within the structure.

Spacegroup visualizer

Submitted by Barbara Reisner / James Madison University on Mon, 01/19/2015 - 22:48
Description

This looks like a great resource to visualize the data contained in the international tables in 3D.

My colleague, John GIlje, recommended this resource to me. It's not something I'll use on a day to day basis because it requires a PC.

Cobalt-Ammine complexes and theories of bonding in metals

Submitted by EGunn / Simmons College on Mon, 01/12/2015 - 12:54
Description

This is a two-week lab in which students synthesize and then characterize three Werner cobalt complexes using IR, UV/VIS and computer calculations using Spartan. Syntheses are based on procedures from:

Angelici, R. J. Synthesis and Technique in Inorganic Chemistry. University Science Books, 1996, pp 13-17.

Borer, L.L.; Erdman, H.W.; Norris, C.; Williams, J.; Worrell, J. Synthesis of trans-Tetraamminedichlorocobalt (III) chloride, Inorganic Syntheses, Vol 31, 1997, pp 270-271.
