EMBS Chapter Talk: Demonstration of 2D NMR Spectroscopy in a Powered Magnet at 25 T

Dr Benjamin D. McPheron will give a talk entitled “Demonstration of 2D NMR Spectroscopy in a Powered Magnet at 25 T” to the Providence Engineering in Medicine and Biology Society Chapter on 27 November 2017 at 6 PM at Roger Williams University in the School of Engineering, Room 124. Performing 2D NMR in powered magnets represents a significant challenge as powered magnets possess poor spatial homogeneity and temporal magnetic field fluctuations.  Resolving off-diagonal cross peaks in 2D spectra requires the spatial homogeneity and time-invariant field strength afforded by persistent mode magnets.  We use ferroshims, sample spinning, and cascade regulation of field strength to enable the acquisition of TOCSY spectra of ethanol using a 16.3 MW resistive magnet that provides a 25 T field.  To our knowledge, this is the first 2D NMR results reported for a powered magnet where cross peaks are resolved.  This talk will discuss the control system design and principal results of this study.
