Marvin suite from ChemAxon

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/09/2020 - 12:10
Description

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
Description

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
Description

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.    

2019 Nobel Prize - Li-ion battery LOs

Submitted by Barbara Reisner / James Madison University on Wed, 10/09/2019 - 20:28

Congratulations to the 2019 recipients of the Nobel Prize - John B. Goodenough, M. Stan Whittingham and Akira Yoshino. It's a well deserved honor!

There are several LOs on VIPEr that talk about lithium ion batteries and related systems. The 2019 Nobel is a great opportunity to include something about these batteries in your class.

I hope to see more LOs in the coming weeks so we can bring this chemistry into our classrooms!

Fourier Transform IR Spectroscopy of Tetrahedral Borate Ions

Submitted by Zachary Tonzetich / University of Texas at San Antonio on Wed, 10/09/2019 - 11:02
Description

This experiment was developed for an upper division Instrumental Analysis course to give students additional experience with infrared (IR) spectroscopy beyond the routine functional group identification encountered in undergraduate Organic Chemistry courses. It shares some aspects with the analysis of gas phase rovibrational spectra typically performed in Physical Chemistry courses, but places a greater emphasis on more practical considerations including data acquisition (using ATR) and interpretation.

Porphyrin-Based Metal-Organic Frameworks

Submitted by Amanda Bowman / Colorado College on Thu, 06/27/2019 - 15:29
Description

This literature discussion explores the physical structures, electronic structures, and spectroscopic characterization of several porphyrin-based metal-organic frameworks through discussion of “Iron and Porphyrin Metal−Organic Frameworks: Insight into Structural Diversity, Stability, and Porosity,” Fateeva et al. Cryst. Growth Des. 2015, 15, 1819-1826, http://dx.doi.org/doi:10.1021/cg501855k.

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sat, 06/08/2019 - 16:41

During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

The Synthesis and Electronic Structure of [NiX4]2- Complexes and the Role of Crown Ethers in Inorganic Synthesis

Submitted by Wes Farrell / United States Naval Academy on Thu, 06/06/2019 - 15:05
Description

This literature discussion aims to have students in an advanced inorganic chemistry course interpret reaction schemes and electronic spectra, relate chemical formulae to molecular structure, and gain an understanding of how inorganic synthesis is planned and executed.  Students should gain an understanding of how counterions and crown ethers affect structure. Question 7 may be expanded to ask students to why pi-donor ability affects ligand field splitting, or as an introfuction to this topic.
