Stuart Elliott

I am a postgraduate student, funded jointly by Bruker and the ESPRC, in the Magnetic Resonance Group at the School of Chemistry, University of Southampton. I graduated from the Master of Physics (MPhys) degree course from the Department of Physics, University of Warwick, 2013. l am involved with Long-Lived States, Dissolution-Dynamic Nuclear Polarization, Electron Paramagnetic Resonance, Gaussian Computation and Pulse Sequence Design. Past research interests involve the design and construction of a "magnetic tunnel" (including superadiabaticity computations) and ultra-fast slice selective experiments.

Project Title: Hyperpolarized Long-Lived Singlet State Nuclear Magnetic Resonance and it's Applications to Microimaging and Microfluidics

Project Supervisors: Professor Malcolm H. Levitt and Professor Marcel Utz

Current Research: Long-Lived Nuclear Spin States in (Rapidly Rotating) Monodeuterated Methyl Groups

Research Description: It is possible to access long-lived nuclear singlet order [1,2] in monodeuterated methyl groups, in the case that a significant chemical shift difference exists between the CH2D protons [3,4]. This occurs when the local environment is chiral, and the CH2D rotamers have different populations. For (N-CH2D)-2-methylpiperidine; the ratio of the singlet relaxation time constant TS to the longitudinal relaxation time constant T1 is found to be equal to 3.1 ± 0.1, over a wide range of temperatures, solvents, and magnetic fields in the "slow-jump" regime [a]. A modified model of the CH2D geometry is proposed to explain the observed ratio of TS to T1.
For (1-deuterio-o-chlorotoluene)chromium tricarbonyl; the longest value of TS approaches 2 1/2 minutes in the
"rapid-rotation" regime [b].
