WebIn magnetic resonance, a spin echo or Hahn echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. Modern nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) make use of this effect.. The NMR signal observed following an initial excitation pulse decays with time due to both spin relaxation and any … WebThe echo time (TE) is the time between the excitation pulse and the peak of the signal. Echo phenomena are important features of coherent spectroscopy which have been used in …

WebSep 15, 2011 · Abstract. In 1950, Erwin Hahn pointed out that spin echoes in Nuclear Magnetic Resonance (NMR) could be used to measure molecular translational motion, an effect made possible because nuclear spins carry a phase determined by the history of their residence in magnetic fields. Oldfield is known for his research in nuclear magnetic resonance (NMR) spectroscopy, and drug discovery. His invention of deuterium and proton NMR methods led to new ways to study the structures of lipids and membranes; his carbon-13 NMR and quantum chemical developments led to new ways to investigate protein structures; his investigations of quadrupolar nuclei led to new research in materials science, geochemistry and catalysis, and his more recent research using NM… hinge interface
