Symmetry of Polyhedral Dice
Description
This activity allows students to manipulate highly symmetric objects and find the symmetry elements that are present.
SLiThErs - Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable
Chip Nataro / Lafayette College
Thu, 12/17/2020 - 14:18
A collection of all of the IONiC VIPEr SLiThErs (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable). These events are short presentations on a topic followed by a period of discussion between the presenter and live participants. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.
Character Tables for Chemically Important Point Groups
Description
You might be familiar with the wonderful symmetry site that was (to my knowledge) originally published on the Jacobs University site and with the name change to the Constructor University site. In addition to having wonderful character tables, the site allowed you to enter reducible representations that the site would then reduce. It would also allow you to the full range of molecular motions or select vibrations (both IR and Raman active). The site has disappeared from time to time and it is unclear if it will ever return.
Synthesis and Group Theory Analysis of MoO2(acac)2
Description
This laboratory experiment is a quick and straightforward synthesis of a MoO2(acac)2 complex. The ligand set allows for two possible geometric arrangements: cis and trans. Using IR spectroscopy along with group theory analysis of the Mo-O stretching modes, students can determine which isomer they formed in their synthesis. NMR spectroscopy is also employed, and confirms the geometric arrangement due to the inequivalence of the acac methyl groups.
Rhenium isocyanide complexes from the Figueroa group
Description
This literature discussion is in honor of Dr. Josh Figueroa, recipient of the 2026 F. Albert Cotton Award in Synthetic Inorganic Chemistry. Josh has done some tremendous work with isocyanide ligands and this paper is but a brief glimpse into this field. The complexes of interest contain carbonyl ligands and isocyanide ligands, so there are plenty of opportunities for students to use group theory to predict the number of IR-active vibrations for these ligands.
From Whiteboard to Spartan: An Integrated Exploration of H2A Molecular Orbitals and Molecular Geometry
Description
This two-part activity offers an integrated approach to understanding molecular orbitals and molecular geometry. In class, students will first engage in a hands on, qualitative construction of the H2O molecular orbital diagram using symmetry principles and a whiteboard.
Nickel-Catalyzed Enantioconvergent and Diastereoselective Allenylation of Alkyl Electrophiles: Simultaneous Control of Central and Axial Chirality (Greg C. Fu)
Description
This literature discussion LO was created for the ACS National Award Winners 2025 collection. Dr. Greg C. Fu for being the recipient of the Gabor A. Somorjai Award for Creative Research in Catalysis 2025 from the American Chemical Society.
Adducts of XeO3
Chip Nataro / Lafayette College
Wed, 02/26/2025 - 14:03
Description
This literature discussion was prepared as part of the 2025 ACS awards collection in honor of Gary J. Schrobilgen, winner of the M. Frederick Hawthorne Award in Main Group Inorganic Chemistry.
Moleculuar Computation and Visualization in Undergraduate Education (MoleCVUE)
Kevin Range / Commonwealth University of Pennsylvania
Fri, 08/09/2024 - 13:01
Description
The MoleCVUE website contains several items that should be of interest to the VIPEr community, especially the activities. Each activity is designed to be ready to deploy in lecture, laboratory, or as homework. There are activities covering all of the major subdisciplines of chemistry (some more than others). Some activities that might be of particular interest to VIPEr are "Group Theory", "VSEPR", and "Electron Configurations of Atoms and Ions". All of the activities are written to use WebMO, but could be adapted for other systems. Most activities are doable with the free or demo versi
Literature Discussion Group Project
Description
This is a literature-based end of semester project. After a semester of introducing literature in the form of typical literature discussions, this assignment is given to small groups. It may be easily amended or added to. Each group is provided with a paper and accompanying questions that are similar to the literature discussions they have done over the semester. They then must use these guiding questions to assemble a presentation to the class. The topics chosen and the guiding questions are designed to provide students with a taste of the many areas of inorganic chemistry that are no
