Nuclear magnetic resonance (NMR) is a technique for determining the shapes and structures of molecules and their interactions. NMR succeeds in discovering the structural characteristics of molecules by observing weak signals from nuclei containing a magnetic property termed ‘spin’.

Great blog on elucidation and education.

 

Research

We are a biophysical research group specializing in the application of nuclear magnetic resonance spectroscopy to biological problems. We are active in the following areas:

1. We perform fundamental studies with solid state zinc NMR spectroscopy and X-ray crystallography in collaboration with the Kastner lab. Zinc-67 is one of the most difficult of all NMR nuclei to study! See also (4).

  

2. We collaborate with the Strein lab to understand the chirally selective solvation of binaphthyl compounds by bile salt micelles. This project includes fundamental studies to gain deeper insight into micelle formation by bile salts.

  

3. We develop and disseminate laboratory and course experiences that effectively introduce undergraduate students to NMR. See our NMR Education Link for more info and dowloads.

 

4. We are investigating the use of alternative data sampling and processing to accelerate and enhance the acquisition of multi-dimensional NMR data.
