NMR Service
 

The Department of Chemistry can offer its Nuclear Magnetic Resonance (NMR) services commercially to external clients.  The extensive facilities available include:
 

Spectrometers

•  Jeol  400 MHz ECP NMR spectrometer with autotune multinuclear probe, broad band decoupling, pulse field gradients and 16 slot autosampler .

•  Jeol 400 MHz Lambda NMR spectrometer with autotune multinuclear probe, broadband decoupling, and 16 slot autosampler. The machines use Jeol’s Delta software.

Both machines have variable temperature capability which includes a low room temperature facility.  The upper limit of the probe is 140 °C.

• Bruker 500MHz Advanc II widebore NMR spectrometer.  Running Topspin software. Temperature range from -20^oC to 180^oC.
   

Experiments Available

Liquid state measurements

1D -         ¹H, ¹³C, 135 Carbon DEPT, ²⁹Si (and Si DEPT), ³¹P, ¹¹B and ¹⁹F are run routinely, but most nuclei can be run on request.  

     1D NOESY and NOE.

2D –       ¹H-¹H COSY and DQF COSY (suppresses uncoupled singlets).

                ¹H-¹H TOCSY.

     ¹³C-¹H correlation: HMQC and HMBC (long range correlations).

                2D NOESY.
 

Solid state measurements

• Magic angle spinning equivalents of most of the measurements mentioned above.

• Quadrapolar measurements including ²H and ¹⁴N.
   

Imaging measurements

• ¹H base imaging measurements on sample ranging from 5cm to 1mm in size. With resolutions down to 20 microns.

 
In addition to the experiments shown above, we would be happy to discuss running other experiments that are within the limitations of the spectrometers.

Data can be provided in a variety of formats including raw files and pdfs in email attachments.  NMR analysis software such as the DELTA software, and CCPN analysis is freely available from the JEOL and CCPN respectively.
