NMR and Reaction Mechanism
Liquid State Spectrometers Based at Edinburgh
NMR is an extremely powerful technique for investigating the structure of chemical species, primarily those in solution, by the radio-frequency interrogation of the sample held in a powerful magnetic field.
- Discuss your project with our highly skilled NMR staff, which can customize techniques and ways of acquiring NMR spectra and design experiments according to your needs.
- Use the fully automated 800MHz NMR spectrometer, offering the highest resolution and sensitivity in Scotland, as well as a suite of automated 600 – 400 MHz spectrometers supporting wide range of NMR experiments for small and large molecules.
- High throughput service underpinned by cryoprobe technology – increased service speed and sensitivity providing cheaper solution to your problems.
- Spectrometers operate with sub-milligram quantities of samples.
- Unique Reaction mechanism analysis equipment that enables monitoring of fast reactions in situ.
- Come and use the facility yourself – after brief training, you can use it on a drop in basis, saving time and organization.
We Can Answer Your Questions
- “What’s the structural composition of this?”

Raman Microscopy and FTIR spectroscopy for material characterisation.
Raman spectroscopy and Infrared spectroscopy are complementary techniques used to observe characteristic vibrational transitions in materials. These can be used to provide a “fingerprint” of the chemical composition of a sample. The provided combination of Raman and/or Infrared spectroscopy with optical microscopy provides a non-destructive way of identifying, characterising and providing surface mapping (on a micron scale) of a wide-range of materials of relevance for materials science, nanotechnology, geosciences, and biosciences among others.
- Discuss your project with our expert researchers, who can propose the best ways of acquiring vibrational spectra from your materials.
- Use the facility yourself – get training on the Raman/FTIR facility suitable for your application; after training, you can use it with available help of expert researchers.
- Get help with analysis of spectral data after measurement; compare the results from infrared spectroscopy with the materials spectral library data.
Note: Requires milligram quantities for measurements
Scanning probe microscopy (SPM) is a microscopy technique for measurements on surfaces and particles covering the sub-nanometer up to the micrometer scale. It can provide information on the morphology (AFM), electrical and magnetic, elastic and frictional properties of surfaces and has a number of applications in material science, chemical physics and life sciences.
- Discuss your project with expert researchers, who can customize techniques and ways of acquiring atomic force microscopy (AFM) or other SPM images according to your needs.
- Get training on SPM for your specific application and access the instrument yourself with real time help available from expert researchers
- Off-line analysis of images can be accessed to provide detailed information on surface roughness, particle size analysis, surface conductivity etc.
We Can Answer Your Questions:
- “What is the chemical composition of this?”
- “What are the properties of the surface of this material?
