NMR Spectrometer: 500-MHz (11.7 Tesla) WB Agilent (Solids) - (Shasta)

Highlighted Research Applications

• Dynamics studies via ²H NMR
• Characterization of quadrupolar nuclei for materials and biological samples
• In situ catalysis investigations via continuous flow (CF) NMR probe for both gases and liquids interacting with solid substrates.

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