Facilities - Solid State Spectroscopy

MSL300 Spectrometer

This spectrometer is used for both routine solid-state NMR analysis, and advanced analysis and technique development.

Two 7 mm MAS probes to cover range from 30-120 MHz.

This spectrometer is used for both routine solid-state CPMAS and MAS spectroscopy, as well as advanced analysis and technique development. The standard spinning speed is up to 4kHz. The large volume results in improved S/N ratio. The type of experiments performed with these include:

» ¹³C, ²⁹Si, ³¹P CPMAS and MAS

» Double resonance experiment, e.g. ¹H-¹³C HETCOR

» Relaxation time measurements

4 mm MAS Triple Resonance Probe (¹H-¹⁹F-¹³C)

The high speed MAS probe is useful for ¹H and ¹⁹F NMR of rigid solids and

measurement of interfaces by cross-polarisation techniques.

4 mm MAS probe to cover range 30-120 MHz

This probe can spin samples up to 12 kHz. Therefore the probe is used for MAS spectra of quadrupolar nuclei, e.g. ²⁷Al, ²³Na, etc.

Static double resonance probe

This probe has a simple solenoid coil incorporated into a single-axis goniometer. It is used to determine the orientation of peptides in lipid bilayers. When used as a ¹H probe it is capable of excellent broadline spectroscopy and relaxation time measurements up to 200^oC.

Static HP probe

This probe is used for ²H broadline measurements. The aim of these experiments is

to measure molecular motion in ²H-labelled materials. Substitution of the probe insert

allows other nuclei to be examined.
