About Liquid-State NMR Spectroscopy

The vast majority of NMR samples are studied in the liquid-state where solid samples are dissolved in the appropriate deuterated solvent. In order to study a sample by liquid-state NMR spectroscopy:
  • Enough sample must be provided to make a 0.6 mL solution of at least 1mM. Usually more sample is required and the solution concentration required will depend on the desired NMR nucleus of interest and experiment. In most cases, solutions of at least 10mM are preferred. If your sample is not appreciably soluble in any known solvent, you may consider using solid-state NMR spectroscopy instead.
  • The sample should be diamagnetic. Paramagnetic samples can be studied by NMR, but the NMR is much more complicated and may not give rise to any useable data.
Services Provided

Depending on your experience using NMR spectroscopy as a means of structural characterization, the NMR facility can perform a variety of functions. For experienced users, staff generally just acquire the NMR data and provide the raw NMR data. For novice users, the NMR facility can prepare the NMR sample, acquire the NMR data, process the NMR data, and provide electronic copies of the processed NMR spectra. For all external service work, a report summarizing the NMR experiments performed and the experimental conditions utilized is included. Experiments are typically completed within 48 hours of sample receipt.

The NMR Facility provides a base service for all samples, which includes:
  • acquisition of desired NMR spectrum at 25 oC
  • e-mailing of raw NMR data
  • sample disposal
  • service summary report outlining the NMR experiments performed, NMR conditions and charges (external samples only)
For an additional charges, the NMR facility can perform the following NMR experiments:
  • Preparation of NMR sample (i.e. dissolution of provided sample in appropriate deuterated solvent and transfer to NMR tube.
  • Standard direct-detect 1D NMR experiments on C-13, F-19 and P-31.
  • Odd-nuclei direct-detect 1D NMR experiments on nuclei such as H-2, B-11, Se-77. Many other nuclei can be studied as well. Please enquire.
  • Indirect-detect heteronuclear 2D NMR experiments on nuclei such as N-15, Si-29. Many other nuclei can be studied as well. Please enquire.
  • Homonuclear 2D 1H-1H NMR experiments such as COSY, TOCSY, NOESY/ROESY.
  • Any of the above experiments can also be performed above or below room-temperature.
  • Processing of the the NMR data into an NMR spectrum. Electronic copies of NMR spectra, including peak picking and integration (where applicable).

Sample Submission Procedure for Western Personnel

The following procedure should be used when submitting a sample for service work:
  1. Contact NMR facility staff via e-mail at chemnmr@uwo.ca or phone at 519-661-2111 x. 82905 to discuss what information you are looking to obtain by using NMR, what solvent should be used, the nature of your sample and what services are required.
  2. Fill out and print the Liquids NMR Service Request - Western Personnel form. Note that the form is a fillable PDF form that can be filled out electronically.
  3. If you are preparing your own NMR sample, bring the NMR sample and the completed sample submission form to the NMR facility. If you are not preparing your own NMR sample, bring at least 20mg of sample in a screw-top vial and the completed sample submission form to the NMR facility.
  4. Requested data will be sent via e-mail generally within 48 hours of sample receipt.
