Course Description:

The purpose of this graduate level skills course is to give an introduction into the application of NMR spectroscopy to those who use this method to solve problems in the fields of chemistry, physical chemistry and biochemistry. The importance of NMR stems from the fact that the extraction of a wealth of information can be readily achieved by the average chemist with a minimum knowledge in quantum mechanics or mathematics. The course will consist of five lectures per week (9:00 a.m.-12:00 p.m.) which will include basic principles and theory of NMR, relating chemical shift and coupling constants to molecular structure, important one and multi dimensional experiments and discuss their application in assignment and structure determination problems. In addition the course involves a laboratory during which students will get hands on experience in acquiring NMR spectra, and perform on line processing and practice assignment and structure elucidation using one- and two dimensional NMR spectra. The organic, inorganic and organometallic aspects of NMR will be taught by Dr. Tomislav Pintauer, and the biochemical perspectives of NMR will be covered by Dr. Rita Mihailescu.

Recommended Text:

We will use “ABCs of FT-NMR” by John Roberts. This book is published by University Science Books and is available via amazon.com or barnesandnoble.com

Grading:

Class Participation: 10%

Instrument Manipulation: 10%

Assignment 80% (Due August 15, 2008)

Inorganic, Organic and Organometallic Students: Each student is required to collect a data set for a compound with unknown structure. The compound can be provided by the student, or if not available, it will be provided by the instructor. Data set collection will include 1H and 13C NMR, as well as 2D COSY. If the compound contains other NMR active nuclei such as P, Si or F, those NMR need to be collected as well. The final report will include detailed structural determination of the unknown compound supported by the NMR measurements. The format of the report will be provided during lectures. Unknown compound cannot be commercially available.

Biochemistry Students: Each student is required to collect a data set for an RNA molecule which will be provided by the instructor. The predicted secondary structure of the RNA will be provided. The student will acquire 2D NOESY on this sample, both in H2O based buffers to obtain information about the imino proton resonances, as well as in D2O based buffers to obtain information about the base H8/H6 and ribose H1’/H2’ region. The final report should contain the assigned imino proton resonances as well as the “NOE walk” with the corresponding assignments in the H6/H8 region.
