Nuclear Magnetic Resonance

Nuclear magnetic resonance (NMR), together with the imaging modality magnetic resonance imaging (MRI), form a powerful non-destructive, non-invasive analytical platform for material characterization. At IMT, both high field (11.7 T) and low field (1.0 T) systems are available. These systems offer the ability to characterize material structure and dynamics in liquid, semi-solid, and solid states. In addition, IMT has the infrastructure required to produce nearly pure hydrogen gas in the para-spin state, an important prerequisite for para-H2(g) hyperpolarization experiments.
