The hamiltonians of NMR. Part IV: NMR relaxation
Concepts in Magnetic Resonance, 1994AbstractUsing the methods presented in our previous discussions of the Hamiltonians of NMR, we describe the processes that lead to relaxation of spin systems. The same nomenclature and methods of Parts I, II, and III have been used to develop a formulation of time‐dependent operators.

NMR relaxation in adsorbed water
Journal of Magnetic Resonance (1969), 1992Abstract The NMR relaxation behavior of the proton magnetization in adsorbed water is investigated. Longitudinal as well as transverse relaxation of the adsorbed water as a whole shows a distinct nonexponentiality and the nature of this nonexponentiality is studied.

NMR Relaxation and Petrophysical Properties
AIP Conference Proceedings, 2011NMR relaxation is routinely used in the field of geosciences to give basic petrophysical properties such as porosity, pore size distribution, saturation etc. In this tutorial, we focus on the pore size distribution deduced from NMR. We recall the basic principle used in the interpretation of the NMR signal and compare the results with other standard ...

NMR relaxation in cellulose pulp
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1996Abstract 1 H NMR has been used to study water dynamics in cellulose pulp. The reduction of water NMR line width with an increase of moisture content was observed. Different temperature dependencies of spin-lattice relaxation time were obtained for different origins of cellulose.

NMR relaxation spectroscopy: Interference effects
Applied Magnetic Resonance, 1999The nuclear magnetic resonance relaxation process and the relaxation spectroscopy is considered in the presence of interference (cross terms) between different spin interactions in a weak-collision approximation. New interference effects are presented.

NMR relaxation times in NMR imaging.
Annals of clinical research, 1984The T1 and T2 relaxation times of pathological tissues can be different from those of normal tissues. It seems that the NMR relaxation times are of great significance in tissue characterization and tumour localization with help of NMR imaging.

NMR Relaxation in Clathrate-Hydrates
1987Clathrate hydrate of tetrahydrofuran was prepared in which the guest molecules contained hydrogen and the water was highly enriched deuterium oxide. Also the opposite case was studied, i.e. the guest molecule was deuterated and the water was normal hydrogen oxide.

NMR relaxation and protein mobility
Current Opinion in Structural Biology, 1993Abstract The increased availability of isotope-enriched proteins and the high sensitivity of proton-detected heteronuclear experiments have stimulated studies of protein mobility via 15N and 13C relaxation. Developments during the past few years include new pulse sequences that yield more reliable values for relaxation rates, and pulse sequences that
