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 400MHz AVIII SmartProbe open-access spectrometer Laphroaig in B18 has a fault with the probe that means the instrrument is OUT OF SERVICE. There is a broken glass insert inside the probe that needs replacing. We cannot give an estimate at this time as to when this will take place.

There are NEW SAMPLE ID rules for the open-access spectrometers. This is to help us produce individual usage reports for these instruments at the end of each month in order that we can charge separate grant codes if PI's desire. Please see the notices on the walls behind each submission PC for full details. In short you need to use your group PI's initials followed by a hyphen (-) and then your crsid followed by the forward slash (/). For example CA-AB220/ABC123-F2 or DRS-AM123/AM-02-F23-35

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 now 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 open-access experiments on all the four spectrometers so that there is standardisation across all instruments, and to make it easierr to produce the usage lists at the end of each month. Andrew will produce a guide to the experiments available on each instrument in the coming months which will be displayed on the wall.

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

We will be putting the price list and guide to experiments at each open-access instrument to aid researchers.

Consumables vending machine should hopefully soon be arriving!!!

Separate grant code charging will start from January 2020.
