NMR: Bruker 200 MHz NMR Spectrometer

Location: 
Dell Butcher Hall 120

Bruker 200 MHz spectrometer for magic angle spinning studies of most spin-1/2 nuclei in solids (most commonly 13C, 29Si, 31P, and 15N but not 1H or 19F) and specialized studies of solutions, including unusual 203Tl and 205Tl solution state NMR capability. 

As a practical matter, the spectrometer is ususually set up to do 13C solid state work with a probe designed for 4mm outer diameter rotors (sample volume about 75 microliters) capable of spinning up to 15 kHz.  With special 4mm rotors, significantly smaller samples can be studied.  Solid state work can also be done with a probe designed for 7mm outer diameter rotors (sample volume about 300 microliters) capable of spinning up to 7 kHz.  Coarse chunks of material cannot be studied in any rotor; the material would first have to be ground.  Only powders or other solids that can be uniformly packed in a rotor can be studied.  With any probe for solid state work, either 1H-X cross polarization or direct X-nucleus pulse experiments can be done.

Instrument Rules:  Specialized work takes priority on the 200 MHz NMR spectrometer.  Please contact Dr. Lawrence Alemany (lalemany@rice.edu) to discuss your research needs and to schedule instrument time.

Training Contact: 
Please contact Dr. Lawrence Alemany (lalemany@rice.edu) for training.  Note that the theory behind and methodology for solid state NMR is very different from that for solution state NMR.  See, for example: http://en.wikipedia.org/wiki/Solid-state_nuclear_magnetic_resonance
