MAGNETIC RESONANCE SPECTROSCOPY; Contact Shirley Fairhurst (01603 450713; Shirley.Fairhurst@bbsrc.ac.uk)
This facility comprises two nuclear magnetic resonance (NMR) spectrometers and an electron paramagnetic resonance (EPR) spectrometer with an ENDOR attachment. Frequent users of the equipment are given training to enable them to work independently. However, interpretation of both NMR and EPR spectra can be difficult in which case every assistance is given.
NUCLEAR MAGNETIC RESONANCE (NMR); Contact Shirley Fairhurst (01603 450713; Shirley.Fairhurst@bbsrc.ac.uk)
The NMR spectrometers are both JEOL instruments; one ( a GSX270) operates at 270 MHz for protons while the other (a Lambda) operates at 400 MHz for protons. Both are multinuclear spectrometers and they are equipped to carry out variable temperature experiments . The Lambda (400 MHz) spectrometer is capable of performing a wide range of sophisticated NMR experiments; it is equipped with a field gradient accessory for advanced 2-dimensional studies and diffusion studies. Typical nuclei investigated include: 1H, 2H, 13C, 14N, 15N, 19F, 31P, 51V, 95Mo but almost any magnetic nucleus can be studied.
ELECTRON PARAMAGNETIC RESONANCE (EPR/ESR/EMR) and ENDOR; Contact Shirley Fairhurst (01603 450713; Shirley.Fairhurst@bbsrc.ac.uk or David Lowe (01603 450742; David.Lowe@bbsrc.ac.uk)
The EPR spectrometer is a Bruker ER200 operating at X-band (9 GHz) and it is fitted with an ENDOR (electron nuclear double resonance) system: experiments can be performed over the temperature range 1.6 to 300 K. Centres containing unpaired electrons, ie. both paramagnetic metals and free radicals (including spin labels) can be studied giving information about the geometrical and electronic structures of the centres. In addition the ENDOR accessory can be used to examine many magnetic nuclei, although it should be remembered that only paramagnetic centres can be studied; this can be an advantage since signals are only seen from the environment of the unpaired electron.
