NMR Pre-Lectures

Dr. Thomas Poon's Organic Chemistry Pre-Lectures are located at http://ochem.jsd.claremont.edu/prelectures.htm. They are very helpful. Spectroscopy 3 deals with carbon NMR and Spectroscopy deals with proton NMR.

Test #1 Chapters 10, 11, 13, and 14

The first test will have 28 questions using the same format as last semester. There will be a few multiple-choice questions as well as reactions and explanations. Let the Problem Sets and textbook examples.

Study, study, study!!!

Scantrons will not be used.

NMR Video

The NMR video used in lecture is located at http://www.youtube.com/watch?v=uNM801B9Y84. The Royal Society of Chemistry has several videos that are interesting.

Also, on our Handouts page, http://www.highlands.edu/academics/divisions/scipe/chemistry/Site/OHandouts.html, the Organic Chemistry Pre-Lectures may be helpful.
