This is a 5-slides on luminescence. It contains introductory and basic description of different examples of luminscence. Since, this is a community of inorganic chemists, only inorganic compounds are discussed as examples.
In my sophomore level inorganic course, I have experimented with the idea of a living syllabus as a way to develop my own specific learning objectives and to help the students connect the material to the tasks that will be expected of them in assessing their learning.
In this literature discussion, students read a paper about a cobalt metallopeptide that imitates the active site of the enzyme nitrile hydratase. Specifically, the model complex is oxidized by air to produce a coordination sphere with both cysteine thiolate and sulfinic acid ligands, much like the post-translationally oxidized cysteine ligands in the biological system.
In this experiment, students will synthesize a cobalt Schiff base complex with varying axial ligands ([Co(acacen)L2]+). They will characterize the complex using various techniques, and may perform computational modeling to predict spectroscopic properties.
This is a literature discussion based on the paper “Spectroscopic Elucidation of the Inhibitory Mechanism of Cys2
This activity is designed to give students a deeper understanding of what post-translational modification does in a metalloenzyme using nitrile hydratase (NHase) as a model system. The metallo-active site of NHase contains a cobalt(III) center that is bound to an unusual coodination sphere containing bis-amidate, cysteinate, sulfenate (RSO-), and sulfinate (RSO2-) ligands.
This exercise makes use of a web-based tool to review quantum numbers of the orbitals of the hydrogen atom and to visualize atomic orbitals in 3D. Students are asked to draw the 1s-, 2p- and 3d-orbitals.
Anne asked the students in her junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article. Each student chose one article from a list of suggestions provided. Student Hayley Johnston chose this article describing a Mn-containing catalyst for carbon dioxide reduction (Jonathan M. Smieja, Matthew D. Sampson, Kyle A. Grice, Eric E. Benson, Jesse D. Froehlich, and Clifford P.
The in-class game Jablinko was designed to make learning excited state transitions fun. To play, a student chooses an excited state by placing a game chip at the top of the board, then the chip can “vibrationally cool” by bouncing through the pegs, and finally “transition” to a lower energy state in the bottom row. The students then compete to be the first to name the transition (e.g. S1 to T1 is called intersystem crossing).
The Sheffield Chemputer is a site that does a variety of calculations including: isotope patterns, element percentages, reaction yields, oxidation states (for transition metal complexes), electron accounting (for metal complexes), VSEPR shape and classification using the CBC method. At the initial point of this post (April 29, 2014) parts of the site are still under development, but it seems to be off to a good start.
