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 Facility team, 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, setting up the spectrometers, modifying pulse programs, automation, DOSY, NUS, Slice Selective NMR, VT, Kinetics, 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 correct from September 2019 can be found at the bottom of the drop down Spectrometers menu - please consult this to ascertain your best route for getting your NMR results!

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 have minimised the amount of paper used in the facility.  If you have a reason for requiring the spectra to be printed please inform us by email, on the submission form or in person.

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

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

You can find more information about the NMR Facility staff members here. If you have questions about any aspect of the NMR Facility, 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 new analytical backup server has been commissioned and the NMR data is now available on it. This means that our old server Scapa is shortly to be withdrawn from service. Full instructions on how to connect to our "NMRarchives" and "NMRshares" shares are available on the Data page.

We have renamed the 400MHz spectrometer in B13 from Florence to Auchentoshan to standardise the names of all of our spectrometers as Single Malt Scotch Whisky distilleries. The Teaching 200MHz spectrometer in B22 has been renamed from Gromit to Springbank - a new sign is on the door!

The 700MHz spectrometer Arran is now working in general use with solid and solution probes. Please liaise with the NMR team or Giuliana Fusco (gf203@cam.ac.uk) for access to this instrument, or if you think your sample could benefit from being run at this frequency. We would welcome existing Cryoprobe trained users using the 700 by themselves if this is something your PI would need.

All four of our open-access spectrometers are soon to be back in use with NMRKiosk. Laphroaig, the 400MHz in B18 has had its Shim Control Board exchanged and the repaired SmartProbe installed and the pulses calibrated. Duncan and I will be getting all the experiments set up for use as it was at the turn of the year. Hopefully it will be back in operation by Friday afternoon.

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.

A price review of the open-access spectrometers has taken place. The charges are now:

£1.00 per short experiment (1H, 11B, 19F, 31P, Quick 1H+COSY, 1H with water suppression etc) dropping to £0.50 for 100+ short experiments.

£4.00 per long experiment (13C+DEPT, PCD, Quick WORKS, Overnight 1H, 19F or 31P etc)

£6.00 per very long experiment (FULL WORKS -1H+13C+DEPT+COSY+HSQC+HMBC)

Future Developments

In future we hope to standardise the naming of the experiments on the open-access spectrometers so that each submission PC has identically named options, which will stop confusion.

We will also be putting the price list at each instrument to aid researchers.
