Nuclear Magnetic Resonance (NMR)

High and Medium Resolution Multinuclear Solids and Liquids NMR Spectroscopy

Our Nuclear Magnetic Resonance Equipment can yield:

• Structural identification
• Structure confirmation
• Atomic composition
• Compound identity
• Component composition of mixtures
• Information on molecular motion
• Conformational information
• Identification of surface rather than bulk species
• Details of low and high temperature effects

We are able to examine:

• Many nuclei; including H, C, F, P, N, Si, Al
• Liquids
• Solutions
• Crystalline or amorphous solids

Industrial applications range from identification of unknowns through quality control to process monitoring, catalysis studies and assessment of the final product. Almost any type of non-ferrous material can be studied although for solution NMR it is necessary for the material to be soluble in one of a wide range of solvents. One advantage of the technique is that it is non-destructive, so that all the sample can be recovered, if desired.

The equipment available at York includes high performance 400 - 700MHz multinuclear spectrometers for studying liquids, of which several have autosamplers, and the Neo700MHz also being equipped with a liquid Nitrogen cooled cryoprobe for greater sensitivity. There’s also a high power 400 MHz spectrometer for studying solids. Variable temperature facilities allow samples to be cooled to 173 K and warmed to 423 K; almost any NMR active nucleus can be studied at York.
