Download the NMR Service Sample Submission Form.

These notes explain how members of this department can make use of the high-field and multinuclear NMR service. This service compliments the open-access facilities offered by the 200, 300 and 400 MHz spectrometers.

All samples must be supplied in a precision 5 mm tube (at least a Wilmad 507PP, New-Era ML5 or MP5 or equivalent).

The NMR service is available for all research workers in Organic Chemistry and makes use of all instruments except the 200, 300 and 400s. Samples may be submitted for analysis to the service, and are returned to you for analysis of the data. You may seek the assistance of the NMR staff for the analysis of your data as necessary. This service is always very busy, so prior to submitting your sample for analysis a few basic considerations are worthwhile.

  • Are the experiments you are asking to be run really necessary?
  • Are they going to give you the information you require? If in doubt, ask a member of the NMR staff.
  • Is the sample you are submitting of a quality suitable for high-field analysis? (see under sample preparation).

To submit a sample to the NMR service, you must fill out a submission form, found in the High-Field NMR lab (00.086). If asking for more advanced proton or heteronuclear experiments to be run, that are not available on the 200 or 400, you must submit the 200/400 MHz spectrum/spectra of your sample (if the sample is not too weak), or a copy of it, with the application form, to show the sample is suitable for analysis. Valuable service time can be wasted by people submitting samples whose major component is some unwanted organic solvent or mere junk! It is also necessary to indicate on the form if you expect to observe signals outside the "usual" shift regions, that is -1 to 11 ppm for proton (e.g. H-bonded protons, metal hydrides, porphyrins) and -5 to 215 ppm for carbon (e.g. silyl derivatives, alkyl iodides, certain ketones). Completed spectra are returned to the collection point in 00.086, together with your sample and/or can be downloaded for analysis.

Service data set naming

All NMR data sets generated by the NMR Service follow a fixed naming format comprising 1) the chemist's two initials, 2) the last four digits of the submission number and 3) the date (four digit day/month) the sample was set-up for data acquisition. Thus, a sample submitted by Richard Ernst with submission number 24109 that was set-up by the NMR staff on 20th May would have the filename re41092005.


Research workers may also ask to be trained to use the high-field facilities themselves.

 Initial training must be given by a member of the departmental NMR staff, not by members of your, or another, research group.

You will also be asked to undergo a (brief) training session with us if you have used NMR instrumentation before. To book instrument time, use the web-based reservation for each spectrometer.
