LINKS

Chem 201 - 2006: These links were posted by Alan Shusterman in 2005. Ron McClard may suggest alternative links in class.

Here are some sites that I have visited myself and thought were useful. Some require that your web browser be equipped with one or more free plug-ins (you might need to "register" to download these), such as Chime.

 

Loads o' Essays

I'm not the only prof who likes to write essays on organic chemistry. These sites contain a huge volume of material.

O=Chem Directory - Dr. Newton at U. Southern Maine has compiled an amazing number of essays here. Many of them contain animations and are interactive. Be prepared to work some problems as you read.

Organic Chemistry - Dr. Reusch at Michigan State U. has written an entire on-line textbook. You need the Chime plug-in (they will help you find it) and you will need to answer questions for the interactive parts of the book.

OCHeM.com - It stands for Organic Chemistry Help eMediatly. OK, their spelling isn't great, but they have some terrific Shockwave animations. I like the hybrid orbitals and the "webcards." Don't worry about the ".com."

Organic Chemistry Help - This is sponsored by the friendly teachers at Frostburg State University. The tutorials are short, but colorful.

Principles of Organic Chemistry - Dr. Nee at Oberlin is on sabbatical this year, but his incredible list of PDF essays (see Class Handouts) lives on. He also has problem sets (and answers) and old exams (and answers), but this material is organized more for his own students than for the greater world. (busted link 8/14/06)

 

IR, NMR and UV-vis Spectroscopy

You can find essays on spectroscopy at most of the sites listed above. Here are some sites that are dedicated to these subjects, and contain material that can be used by beginners.

WebSpectra - Problems in NMR & IR Spectroscopy - Ginormous list of NMR and IR problems scaled by difficulty. The NMR spectra are crisp images, but you need to use the zoom control to see coupling patterns, measure peak positions and integrals.

Analyzing NMR Spectra - Quiz Yourself - This site contains two kinds of quizzes: assign signals in a spectrum to the protons that make them, and identify the compound that makes a spectrum. You get your answers right away and there is a long list of compounds and spectra so it never gets boring. Warning: the site is a little old and doesn't work 100% with newer web browsers, but the stuff that does work is very worthwhile.

Science of Spectroscopy - This site tells you basic stuff, like "what is light?" and advanced stuff about NMR, IR, UV-vis, and even some strange techniques that no organic chemist has ever heard of. The Theory wiki is probably what you want, but don't be shy about poking around because this site is always changing.

Organic Compound Identification using IR Spectroscopy - Dr. Volland of Bellevue CC has boiled it down into one page.

Spectroscopic Tools - Data Wizards - Spectra give lots of numbers. Can't interpret your numbers? Try typing them in a "wizard" box. Scary!

1H NMR Chemical Shift Predictor - This "wizard" lets you enter a partial molecular formula, then it predicts the chemical shift. Alkyl CH only. The spectroscopy class at Colby College also provides links to other interesting tools.

 

Looking for more???

These pages go way beyond Chem 201/202, but are useful resources for Reed students who would like to learn more about spectroscopy in organic chemistry.

Organic Structure Elucidation - A Workbook of Unknowns. This site contains a list of "unknown" problems complete with NMR (proton & carbon), IR, and MS data. Easy, moderate, and difficult problems are all available.

Do you have a web site that offers useful instruction or practice problems for advanced undergraduates? Contact me and I'll consider posting it here.
