A Remote Experiment in Earth Field Nuclear Magnetic Resonance

Part II: Applications in Chemistry, Geology and Medicine

Abstract

Magnetic Resonance Imaging (MRI) is a versatile visualisation technique in medicine. The contrast between certain tissues is enhanced by contrast agents which alter the longitudinal and transversal relaxation times. Spatial magnetic gradients are relevant in these imaging techniques as well as in diffusion studies of water content in minerals. The heteronuclear coupling of hydrogen and fluorine atoms allows for structural analysis of chemical compounds.
