Physiol Chem Phys Med NMR. 1996;28(4):205-38
Authors: Akber SF
The spin lattice relaxation time (T1) and spin spin relaxation time (T2) of water protons of normal human and animal tissues are archived to up-date those already published. The mechanisms for water proton relaxation times of tissues are reviewed with reference to water content, paramagnetic ion, protein dynamics content and organ weight.
[Question from NMRWiki Q&A forum] bulk water relaxation dependence on temperature
bulk water relaxation dependence on temperature
Is liquid water's relaxation rate strongly dependent on temperature, and does anyone have a link to a good online article with the dependency equation?Thanks!
Check if somebody has answered this question on NMRWiki QA forum

Protein backboneN NMR spin relaxation rates are useful in characterizing the protein dynamics and structures. To observe the protein nuclear-spin resonances a pulse sequence has to include a water suppression scheme. There are two commonly employed methods, saturating or dephasing the water spins with pulse field gradients and keeping them unperturbed with flip-back pulses....

The paramagnetic contributions to water proton spin-lattice relaxation rate constants in protein systems spin-labeled with nitroxide radicals were re-examined. As noted by others, the strength of the dipolar coupling between water protons and the protein-bound nitroxide radical often appears to...

Authors: Prosser S, Peemoeller H
Proton spin-lattice relaxation measurements were performed in 10 mM lysozyme solution as a function of temperature and degree of substitution of solvent H2O with D2O. The results show that in the temperature range from 274 to 323 K, the intermolecular lysozyme proton water proton coupling contributes appreciably to the observed water proton...
