NMR Spectrometer: 900-MHz (21.1 Tesla) Varian NMR System (Solids & Liquids) - (Everest) - (subscribed through Sept. 2013)

Highlighted Research Applications

• Characterization of quadrupolar nuclei for materials and biological samples, including fast magic angle spinning (MAS)
• High-temperature, solid-state capability for investigating catalytic materials
• Structural biology
  • Protein structure and dynamics, solution or solid-state
  • Nucleic acids structure and dynamics, solution or solid-state

Researchers may operate the system independently and can be trained to manage fully self-directed operations. Collaborative work with staff scientists is possible and encouraged.
