Hole-burning diffusion measurements in high magnetic field gradients

EE Sigmund, WP Halperin - Journal of Magnetic Resonance, 2003 - Elsevier
We describe methods for the measurement of translational diffusion in very large static
magnetic field gradients by NMR. The techniques use a “hole-burning” sequence that, with …

Effects of mesoscopic susceptibility and transverse relaxation on diffusion NMR

DS Novikov, M Reisert, VG Kiselev - Journal of Magnetic Resonance, 2018 - Elsevier
Measuring molecular diffusion is based on the spatial encoding of spin-carrying molecules
using external Larmor frequency gradients. Intrinsic variations of the Larmor frequency and …
