Hyperpolarized and thermally polarized quadrupolar noble gas nuclei studied by nuclear magnetic resonance spectroscopy and magnetic resonance imaging
This dissertation consists of several studies of two quadrupolar nuclei, 83Kr and 131Xe, with nuclear spin states of I = 9/2 and I = 3/2, respectively. These nuclei possess a nuclear electric quadrupole moment that strongly interacts with the surrounding electric field gradient (EFG). The quadrupolar interactions in these noble gas atoms dominate the longitudinal (T1) spin relaxation. To fully study these nuclei, high non-equilibrium nuclear spin polarization, referred to as hyperpolarization (hp), is generated using spin exchange optical pumping (SEOP). By employing this technique, enhanced ...
