MAGNETIC RESONANCE FACILITY
The Department of Chemistry’s Magnetic Resonance Facility underwent a major upgrade in 2006 and in 2011 with the addition of three NSF funded spectrometers: Varian Direct Drive 500 MHz and 600 MHz NMR’s and a Bruker EMX PLUS EPR.
The Varian Direct Drive 500 MHz NMR is the routine spectrometer for the facility for research and undergraduate teaching which has dual capabilities in both liquids and solids experiments. The spectrometer’s capabilities are largely based on the diverse capabilities of its probes:
- Broadband X{1H} (frequency range of 50-200 MHz) along with 19F capability.
- High sensitivity Inverse-X{1H } probe for low concentration and natural product samples.
- Triple resonance (HCN) probe for protein and biomolecular structural studies.
- A 7 mm pencil broadband X{1H } probe with 200 watt wide bore amplifier for CPMAS solid state NMR.
Other notable specifications: 
- 3 channel operation
- Variable temperature capability
- VnmrJ2.2 C software on RedHat Linux
- Solidpack software for solids NMR experiments.
- Biopack software for biomolecules multidimensional NMR.
- Rate per hour $7.20 in house or external usage.
The Varian Direct Drive 600 MHz NMR is the instrument of choice for high resolution research needs with specific capabilities for protein and biomolecular structural research.
- 4 channel operation which includes deuterium decoupling.
- Triple resonance (HCN) probe for protein and biomolecular structural studies.
- C13 enhance cryo-probe for protein and low concentration samples.
- Variable temperature capability
- VnmrJ2.2 C software on RedHat Linux
- BioPack software for multidimensional NMR experiments
- Rate per hour $9.00 in house or external usage.
The Bruker EMX Plus EPR is a newly installed spectrometer which will allow studies on the effect of unpaired electron systems in protein structure, bioinorganic and inorganic molecular systems.
- X-band spectrometer with a premium X microwave bridge.
- Xenon software on a SUSE Linux.
- ER 4199HS cavity with high signal to noise.
- Accessories include an AquaX capillary system and liquid nitrogen VT controller.
