We operate 600 MHz high-resolution solid-state nuclear magnetic resonance spectrometers (wide-bore 14.1 T magnets) equiped in the SKLee Lab (with fast-spinning 1.3, 1.9, 3.2, and 7 mm triple resonance probes), yielding high-resolution spectra for diverse oxide earth materials. The state-of-the-art advanced solid-state NMR pulse sequences are being developed and optimized for the study of diverse earth materials under compression.
