Electronic spectroscopy

24 Feb 2010
Description: 

This is a website which links to a wide variety of good quality YouTube mini-lectures on basic topics in chemistry, mathematics, physics and a variety of other sciences.  Each video is about 10 minutes long and many go through example problems slowly and completely.  

Course Level: 
Prerequisites: 
Corequisites: 
Learning Goals: 

A student will be able to choose a topic they would like to learn more about, either for review or enrichment, and gain a basic understanding of it.

Related activities: 
Implementation Notes: 

I am posting this on our course management site for my Inorganic Chemistry course to help them review some topics they might have forgotten.  This site will be most useful in my general chemistry course both in chemistry content and for students who need a mathematics review before beginning some topics.

Bioinorganic Chemistry- Metals in Purely Structural Roles

Submitted by Sheila Smith, University of Michigan- Dearborn
Evaluation Methods: 
This is mainly a discussion leader. Assessment focuses on student's ability to apply this same logic to other systems at a later time
Description: 
This is a discussion leader to bring students into the topic of "Metals in Biochemistry- Structural Roles" by reminding them of pieces they already know from General Chemistry and other courses.
Learning Goals: 
A student should be able to apply their knowledge of Lewis acid-base theory to predict the amino acids that will bind a particular metal. A student should be able to apply their knowledge of transition metal oxidation states to predict whether the metal can play a redox role. A student should be able to apply their knowledge of VSEPR to predict structure.

Bioinorganic Techniques in a Nutshell

Submitted by Elizabeth Jamieson, Smith College
Evaluation Results: 
I believe that the students found the website helpful - especially since they hadn't encountered many of these bioinorganic techniques before.  I didn't assess it in a formal way.  
Description: 
This website is from the Center for Metalloenzyme Studies at the University of Georgia.  It contains brief summaries of common techniques used in bioinorganic chemistry.  I really liked that for each technique lists what kind of information you can obtain, as well as what the limitations of the method are.  It also provides examples of what kinds of questions can be answered with each technique.  It does not provide in-depth information about how each method works, but rather simply lists the basic facts about each technique.  
Subdiscipline: 
Course Level: 
Learning Goals: 
I used this website when teaching an upper level elective in bioinorganic chemistry as a way for the students to get an idea of what could be accomplished with these various techniques. The idea was for them to have a place to go to learn the basics about different techniques when they encountered them when reading journal articles.

Introduction to High Resolution Spectroscopy

Submitted by Adam Bridgeman, The University of Sydney
Description: 

http://assign3.chem.usyd.edu.au/spectroscopy/index.php

A series of Java tools for learning about the relationship between molecular parameters (size, mass etc) and the form of the spectral trace. These cover rotational, vibrational, ro-vibrational and electronic spectroscopy.

Prerequisites: 
Course Level: 
Learning Goals: 

A student should be able to explain how the properties of a molecule relate to the form of its rotational and vibrational spectrum. A student should be able to explain how the lines in a high resolution spectrum are relate to the energy levels of the molecule.

Implementation Notes: 

This site is used in lectures to show graphically how the energy levels and spectrum are related. It is also used as a self-learning tool by students and is useful for those whose level of mathematics might restrict their enjoyment and understanding of spectroscopy.

Time Required: 
Each tool requires around 30 minutes. The whole site takes many hours.

Angular Overlap Model Spreadsheet

Submitted by William F Coleman, Wellesley College
Description: 

This spreadsheet allows students to build complexes of a variety of geometries and to then use the angular overlap model to explore d-orbital energies when interacting with ligands whose esigma and epi energies can be varied.  

http://academics.wellesley.edu/Chemistry/Flick/Excel/angoverlap.xls

Prerequisites: 
Corequisites: 
Learning Goals: 

To explore a highly parameterized model and to deepen student understanding of metal-ligand interactions.

Implementation Notes: 

I gave one of my 10-minute quizzes (these are due electronically by midnight on the day they are given) based on this spreadsheet early last week and all 20 of my inorganic students did it perfectly.  Either the spreadsheet was helpful, or the quiz was meaningless.

Inorganic Challenges

Submitted by Patrick Holland, Yale University
Description: 

The Interactive Inorganic Challenge Forum is a resource for inorganic chemistry teachers who want to incorporate team learning questions (“Challenges”) into an upper level undergraduate inorganic course. Through this site, teachers can exchange their ideas with others who have used inorganic chemistry Challenges. As a result, students benefit from field-tested group questions.

Interactive Spreadsheets for Inorganic Chemistry

Submitted by Lori Watson, Earlham College
Description: 

This web site contains a number of interactive spreadsheets, most of which are applicable to inorganic chemistry (or a physical chemistry class that uses inorganic examples).  Here's the list of the most relevant for most inorganic classes:

 

ABC kinetics - interactively plot concentration versus reaction extent for A, B and C in A -> B -> C by varying k values

angular overlap model - explore the angular overlap model for d-orbital splitting in complexes by designing various geometries of complexes and varying the parameters es and ep

complexation of silver ion - explore the concentration of various silver species in ammonia as a function of ammonia concentration - can be generalized by varying the Ksp and formation constants interactively

general complexation - explore the distribution of complex species as a function of the concentration of ligand X for MXn with n = 1 - 6 by varying the formation constants

reducing irreducible representations - interactive spreadsheet for reducing reducible representations of 12 common point groups

reversible kinetics - explore concentrations of A and B for A <=> B as a function of time by varying k values - also shows the reaction quotient, Q, and the ratio of Q/K


Prerequisites: 
Corequisites: 
Learning Goals: 

Depends on which spreadsheet you're using!  

Implementation Notes: 

Some of these spreadsheets require Visual Basic which is apparently not supported on Excel 2008 for Mac.  You can use all PC versions of Microsoft Office, however, and may be able to use other products to convert to a Mac-readable format.

House: Inorganic Chemistry

Submitted by Adam R. Johnson, Harvey Mudd College
Description: 

House (Inorganic chemistry):  The book is divided into 5 parts:  first, an introductory section on atomic structure, symmetry, and bonding; second, ionic bonding and solids; third, acids, bases and nonaqueous solvents; fourth, descriptive chemistry; and fifth, coordination chemistry.  The first three sections are short, 2-4 chapters each, while the descriptive section (five chapters) and coordination chemistry section (seven chapters covering ligand field theory, spectroscopy, synthesis and reaction chemistry, organometallics, and bioinorganic chemistry.) are longer.  Each chapter includes references (both texts and primary literature) for further reading, and a few problems (answers not available in the back of the book). 

I thought the text was generally good.  This text felt aimed at the introductory one-semester inorganic course offered at most schools rather than an advanced (senior/grad) course.  Although MO theory is developed in the text, most of the coordination chemistry is described using crystal field theory, though a short section on MO theory for complexes is included.  The sections on descriptive chemistry of the elements are very good and not overloaded with too much information, and the writing style (throughout the text) is easy to read and conversational.

My main complaint about the book, and this may seem petty, is that the molecular orbitals (throughout) do not accurately depict the way actual orbitals look;  they are too "pointy." 

The list price for the student text is $99.95 for a paperback, 864p version.

The Magic Furnace: The Search for the Origins of Atoms

Submitted by Maggie Geselbracht, Reed College
Description: 

By Marcus Chown
Oxford University Press, 2001
240 pages, ISBN 0-19-514305-1

This popular science book is very readable and fascinating for anyone with an interest in chemistry, astronomy, and the origins of the elements. The story weaves together the history of atomic theory, spectroscopy, radioactivity, and astrophysics to build a compelling tale that is hard to put down. Either the whole book or selected chapters would make a great supplemental text for a general chemistry or inorganic chemistry course, particularly if one wished to go into nucleosynthesis in more depth than most textbooks cover.

Miessler and Tarr: Inorganic Chemistry, 3rd. Ed

Submitted by Nancy Scott Burke Williams, Scripps College, Pitzer College, Claremont McKenna College
Description: 

Miessler and Tarr is an inorganic textbook which is is best suited to an upper-division one-semester inorganic course, though there is more material than can be covered in a single semester, so some choice of topics is necessary.  It is very well suited for a course oriented around structure, bonding, and reaction chemistry of transition metal compounds, but is very limited in its treatment of solids, main-group, descriptive chemistry, and bioinorganic.  Pchem would be helpful but is not necessary.  In particular, the treatment of MO theory is very in-depth.  The quality of end-of chapter problems is generally good.  The book is fairly readable, giving it an advantage over some of the more "reference work" style textbooks, but as a result, is a less useful text to have on your bookshelf five years hence.  Pearson Higher Ed. suggests a retail price of $144.20.
