Useful Data

Click here for Gottlieb's paper on chemical shifts of common solvents as trace impurities in NMR spectra. This is posted with the understanding that it will be downloaded only for personal use as understood through the "fair use" doctrine of copyright.

Click here for an illustration of the effect of turning on J-coupling on a two spin (4-state) AX spin system. Note that either a positive or a negative J gives the same spectrum, but that the assignments of which peak is which varies. In other words, you cannot assign the sign of J based solely on a regular 1-D spectrum.

These are a few useful data for silicon compounds where the Si is not necessarily an alcohol protecting group.

This is a strongly recommended paper to help you learn to assign 1st order coupling patterns: "A Practical Guide to First-Order Multiplet Analysis in ¹H NMR Spectroscopy" J. Org. Chem. 1994, 59, 4096-4103. 

Cool outside links

Joseph Hornak at Rochester Institute of Technology has an OUTSTANDING on-line NMR "text". It goes over much of the material we discuss with regard to the vector model, relaxation, pulses, etc. A very nice thing about it is that there are lots of cute (and instructive!) animations. There is also a similar "book" on magnetic resonance imaging (MRI).

Jeol makes NMR spectrometers, but their NMR site isn't as good as the MS site. Some of the spectrometers at ISU were made by Varian, and others by Bruker. The Varian site has some cool stuff about their history in the NMR biz. This is a longer version of it and includes their other businesses.

A series of lectures on NMR given by Prof. Rzepa at Imperial College. These cover lots of the material I did and are written out, which you may find helpful. There are also good links to other places.

Pacific Lutheran University maintains a nice FID Archive of organic samples.

A very cool database of NMR data of biomolecules (BioMagResBank) is maintained at UW Madison.

The Institute of Organic Chemistry and Structure Analytics at Potsdam has a GREAT site for learning NMR with lots of useful stuff, like an NMR periodic table, information about NMR solvents, and an electronic set of tables sort of like Pretsch's book. It also has a program that calculates C-13 chemical shifts for aromatic compounds.

The University of Florida maintains a site with lots of good professional information on topics for NMR.

A site called NMR Concepts is maintained at the University of Rhode Island. They offer short courses, and so on, but also have an on-line journal you might wish to peruse.
