Welcome to the Department of Chemistry NMR Service  

We provide NMR analytical chemistry services to:

  • Research workers within the department
  • Research workers in other University departments
  • External customers (please contact Dr Peter Grice, who will be able to answer your enquiry)

Equipment

  • 13 high field superconducting magnet systems, with associated hardware, enabling a wide variety of experiments at various field strengths 
  • A separate Solid State NMR facility for the group of Professor Clare Grey  (more information available at the Grey Research Group website)

For more information about the individual instruments and their capabilities, go to the NMR Spectrometers page.

Services and supplies

  • A large range of deuterated solvents and NMR tubes.
  • Other chemicals of use in NMR spectroscopy.  
  • Assistance with basic interpretation of results
  • Tips on how to process your spectra to get the best results
  • Help with TopSpin, planning experiments, running DOSY spectra and using the Dynamics software to process them, Non Uniform Sampling (NUS) and much more.

TopSpin 4.x is now supplied free by Bruker for academic use.For new members of the department wishing to get a copy of TopSpin for themselves - please see the instructions available below for getting it installed and using it to process your spectra. We recommend that all users of the NMR facilities view their spectra on a computer in order to extract the most information.

We are generally always busy, with a lot of samples in the in-tray.  You may receive an email with your data enclosed before your spectra have been checked and your sample is returned.  If you have checked your data personally and are happy with the results please inform us, and we will put your NMR sample tube out to be collected.

As a rule we DO NOT print the spectra out because most of our users are happy with the electronic data, and we are trying to cut down on the amount of paper used in the section.  If you require the spectra to be printed please inform us on the sample submission form by circling the appropriate option.

For more information on what the spectrometers might do for you, please contact one of the NMR Service staff:

Or email all the NMR team at once using nmr@ch.cam.ac.uk

You can find more information about the NMR Service staff members here.  If you have questions about any aspect of the NMR service, email, phone or drop by our office in the basement (Room B28).

We now have a twitter account - @camnmrservice - https://twitter.com/camnmrservice/  We will use this for status updates, important news and tips.  Any good questions we get through other channels may well end up here as general information for everyone.  We look forward to receiving your tweets!

Current status

All of our instruments are operational at present, although Cragganmore (Service 400MHz QNP Cryoprobe in B28) is unable to run 19F or 31P spectra until further notice.

Lagavulin (B25) open access spectrometer has had the probe and shim system cleaned following a smashed tube incident.  There was a considerable amount of dirt, so we ask users to clean their tubes with tissue before putting them in the sample changer.  If you suspect a tube has smashed inside the probe or bore of the magnet (the spectra may all look the same or subsequent spectra will show nothing) then send an email to nmr@ch.cam.ac.uk and place a note on the submission PC keyboard stating DO NOT USE.

Future Developments

We obtained some funding from the School of Physical Science to help update one of our old spectrometers – they pay 50% and 50% will come from accumulated NMR charges.  The new machine has been ordered and should arrive in April or May.  The walk-up machine Lagavulin will migrate to B12 (and use the SVL400 magnet) and continue to be walk-up access.  The new machine will replace Lagavulin in B25 and will also become walk-up access after a period of testing and set up.  The new machine will have much higher sensitivity and should allow users to record full “works” spectra on concentrated (10-20mg) samples during the day … our target is for this to take 20 minutes!  The more standard overnight experiments should need less material (by a factor of ~3) or work better with the same amount of material when compared to our existing walk-up machines.  The new machine will have some new capabilities like running 13C spectra with 19F decoupling.  Visit us in the NMR service room (B28) if you need more information.

We are also in the process of planning a series of video tutorials to help you get the most from your NMR experience.  These short (2-3 minutes) training videos will cover most of the common problems and questions we encounter.
