Welcome to the Department of Chemistry NMR facility

We provide NMR analytical chemistry services to:

  • Research workers within the department
  • Research workers in other University departments
  • External customers (please contact the NMR Service, 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.

A Spectrometer Comparison Chart for October 2018 has been updated with the latest spectrometer information and can be found at the bottom of the drop down Spectrometers menu. 

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 have a reason for requiring the spectra to be printed please inform us by email or in person.

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 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

The next training sessions for the open-access instruments Laphroaig and Lagavulin will take place on Wednesday 24th at 10am and 1pm. If you want to attend either session please register your interest by emailing nmr@ch.cam.ac.uk. Subsequent sessions will be at 10am and 1pm for the rest of the week as required apart from Friday when there will be no training. Our twitter account - see above - will have up to date information and service updates.

Our new 400MHz spectrometer Tobermory to replace Lagavulin in B25 is now available for use by researchers The new Prodigy probe and Avance Neo console which give increased sensitivity have been thoroughly tested by the NMR Service team. It will be available for a mix of walk-up access and specialist users.  Everyone will need training before using this spectrometer.

For walk-up access a limited range of experiments will be available.  These will correspond to the overnight 1H, 13C, DEPT (PCD) and FULL SUITE (1H, 13C, DEPT, COSY, HSQC, HMBC) experiments on the other walk-up spectrometers but will give rather better results and this queue will run all the time.  We will also have a longer 31P experiment for dilute samples.  We may also add other experiments that exploit the capabilities of the new instrument.  Having the queue for longer experiments running all the time means this is not going to be a good place to run quick 1H spectra. Data from Tobermory might not be processed by old software versions, however Topspin is free for academic use and we have details of how you can get it above. You will be able to access your data via Scapa in the same way as you do for the other instruments.

Tobermory has some unique capabilities and so won’t be in walk-up mode all the time.  We are working to provide a booking page so you can see when it is available.  Tobermory is our only spectrometer that can run 19F-13C correlation experiments and will probably be our most sensitive option for 7Li, 11B, 31P and other odd nuclei.

We have put some technical details and photographs of Tobermory on the spectrometers page recently.

The magnet on the 700MHz spectrometer Arran in B14 has been refurbished and re-energised. Bruker scientist Julian reimaged the PC from Linux to Windows .  The spectrometer and probe has passed end testing and we are nearly ready to put it into operation. We have replaced the console with an AVANCE II+ one that is suitable for both solution and solid state NMR.  This work will make this instrument much more adaptable, applicable to more groups research and secure its future for another decade or more.  Please see us in the NMR Service room if you have any questions. Management of this spectrometer will be by Dr Janet Kumita on behalf of the Dobson/Vendruscolo/Knowles groups - please contact her - jrk38@cam.ac.uk - for access if required.

Fingers crossed for a working 700MHz system by late October!!

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

Future Developments

We are now deciding on the deployment of the former Ley Group 600MHz spectrometer.  The emphasis will be on throughput and using the dispersion gained by virtue of the higher field. Further details will be announced in due course. The instrument will be available for use by all research groups in the department.
