Magnetic Resonance Instrumentation Facilities

Nuclear Magnetic Resonance Facilities

The Chemistry Department currently operates a state-of-the-art Bruker Avance DRX-400 NMR spectrometer, with proton frequencies of 400 MHz. 

Bruker DRX-400

Bruker DRX-400 is equipped with a variety of probes with capabilities ranging from high sensitivity for proton, carbon, phosphorous, and fluorine to broad band probes allowing observation of a large number of more exotic nuclei. The instrument set up for rapid throughput of routine samples.

This instrument is capable of doing most modern liquid phase NMR experiments including state of the art two and three dimensional techniques with pulsed field gradients. It is available to departmental users to solve structural problems requiring high resolution capabilities. To increase access to the instrument, it is equipped to transfer data to personal computers and workstations within the department.

Electron Spin Resonance Facilities

There are two ESR spectrometers in the chemistry department; a Varian E-3 and a new Bruker EMX spectrometer. Both are equipped with low-temperature cryostats; the Bruker has an Oxford liquid helium flow cryostat and controller. The Bruker is configured with an X-band microwave bridge, which in turn is coupled to a cavity capable of performing both parallel and perpendicular mode experiments. These facilities allow the measurement of a full range of samples under a variety of conditions, while looking at transitions for both S=n/2 and S=n states.  For additional information visit our EPR site.
