Analytic treatment of nuclear spin-lattice relaxation for diffusion in a cone model

, 2011
We consider nuclear spin-lattice relaxation rate resulted from a diffusion equation for rotational wobbling in a cone. We show that the widespread point of view that there are no analytical expressions for correlation functions for wobbling in a cone ...

Proton relaxometry of tree leaves at hypogeomagnetic fields

Frontiers in Plant Science
We report on a cross-species proton-relaxometry study in ex vivo tree leaves using nuclear magnetic resonance (NMR) at 7µT. Apart from the intrinsic interest of probing nuclear-spin relaxation in biological tissues at magnetic fields below Earth field ...

From Power‐Law to Correlation‐Time Distributions: A Unified Framework for the Analysis of Nuclear Magnetic Relaxation Dispersion (NMRD) Profiles of Complex Biological Systems

Magnetic Resonance in Chemistry, Volume 64, Issue 5, Page 494-505, May 2026.
1H NMRD profiles of biological systems often follow a power‐law dependence rather than a Lorentzian dispersion. This behavior can arise from a broad distribution of correlation times, weighted by 1/τ 1−α. Validated across diverse systems such as sedimented proteins and biological tissues, this framework provides a physical interpretation of power‐law ...

MC BTS: Simultaneously Resolving Magnetization Transfer Effect and Relaxation for Multiple Components

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2538-2553, May 2026.
ABSTRACT Purpose To propose a signal acquisition and modeling framework for multi‐component tissue quantification that encompasses transmit field inhomogeneity, multi‐component relaxation and magnetization transfer (MT) effects. Theory and Methods By applying off‐resonance irradiation between excitation and acquisition within an RF‐spoiled gradient ...
