Nuclear Spin-Lattice Relaxation in Phenylacetylene.
Spin relaxation is due to fluctuating magnetic fields present in solutions. These fields have a different nature and are ultimately due to spin-spin, spin-field and spin-rotation interactions. The contributions from different mechanisms are additive to the total relaxation rate. S ynonyms for T1 relaxation include longitudinal relaxation, thermal relaxation and spin-lattice relaxation. The meanings and implications of these synonyms will become apparent shortly.... Bloch F. Nuclear induction (pdf). Phys Rev 1946; 70:460-474,1946.

Nuclear spin relaxation - Nuclear Magnetic Resonance (RSC.
The use of nuclear spin relaxation measurements in the study of liquid crystal dynamics goes back only to 1969, to work by Doane (1), Blinc (2), Cabane (3) and their coworkers. Practically all of the early work relied upon proton relaxation measurements (4,5), and several major mechanisms and relaxation pathways were identified for thermotropic.
Nuclear Spin Relaxation in Liquids | Theory, Experiments, and.
Nuclear magnetic resonance (NMR) is widely used across many fields because of the rich data it produces, and some of the most valuable data come from the study of nuclear spin relaxation in solution. While described to varying degrees in all major NMR books, spin relaxation is often perceived as a difficult, if not obscure, topic, and an accessible.
Nuclear spin relaxation.
The diamond nitrogen-vacancy (NV) center [] is a leading platform for various quantum technologies such as quantum communication, quantum computation, and nanoscale sensing [2-8].The electronic spin of the NV center and a few surrounding nuclear spins form a hybrid quantum register [9-11].Important advantages of this solid-state quantum register include the long electron and nuclear spin. Spin lifetimes [6,7], to spin alignment by specific mechani-cal modes either at the Larmor frequency or in the rotating frame [8,9], to resonant amplification of mechanical oscil-lations [10]. In this Letter, we report direct experimental evidence for accelerated nuclear spin relaxation induced by a single, low-frequency mechanical mode.

For ease of comparison, the initial polarization in (a) is replotted. In (c), we show the nuclear spin relaxation dynamics vs the Dwell time to the NG boson for pumping times τ p = 100 s (400 s) respectively with the solid lines providing a visual guide. It is clear that at long times the double-nuclear-spin domains reach the same thermal. The observation that the spin-lattice relaxation (R 1Z)...

Electric Field. The nuclear magnetic spin‐lattice and transverse relaxation processes for the 1 H and 2 D nuclei in purified elastin (ligamentum nuchae), exchanged and hydrated with excess D 2 O, have been studied in the temperature range 276°-340°K. The 2 D relaxation results clearly show the presence of D 2 O (1) external to the bulk elastin sample, (2) in spaces within the bulk elastin, and (3) as an.
T2 (spin-spin) relaxation - Questions and Answers in MRI.
The carbon-13 spin-lattice relaxation times of the carboxyl carbons of acetic acid and its deuterated analogues (CH 3 COOD, CD 3 COOH, CD 3 COOD) have been measured by nuclear magnetic resonance spectroscopy. These measurements reveal that the methyl protons and the hydroxyl proton contribute roughly equally to the total dipolar relaxation of neat acetic acid. Nuclear spin may be related to the nucleon composition of a nucleus in the following manner: Odd mass nuclei (i.e. those having an odd number of nucleons) have fractional spins.... Another relaxation mechanism called spin-spin relaxation (or transverse relaxation) is characterized by a relaxation time T 2. This process, which is actually a.

To the NZS due to electron-electron-nuclear relaxation, and x Unlike the case of a single homogeneous line, in which T 1n is the spin-lattice relaxation time for the NZS arising off-resonance irradiation of the EPR line drives polarization from processes other than the electron-electron-nuclear transfer by perturbing the dipolar spin. The nuclear magnetic relaxation dispersion profile thus obtained was interpreted with a recently developed model, allowing for both inner- and outer-sphere relaxation. The relaxation enhancement for the carbon-13 nuclei in raffinose was studied under high-resolution conditions at three magnetic fields, whereas the sugar proton PRE was measured. The analogous process involving electron spins was discovered by Purcell and termed ``Barnett relaxation''. We revisit the physics of the ``Barnett relaxation'' process and correct the estimate for the Barnett relaxation rate. We show that nuclear relaxation can be orders of magnitude more important than Barnett relaxation.

Nuclear Spin Relaxation in Viscous Liquids: Relaxation Stretching of.
A theory of nuclear spin relaxation in paramagnetic systems, allowing for the electron spin relaxation to be in the slow motion regime, is presented. The formulation is general and can, for example, be used to derive formally the modified Solomon-Bloembergen equations. The theory is applied to the specific problem of nuclear spin lattice relaxation caused by the dipole-dipole interaction. Nuclear Magnetic Resonance (NMR) - Relaxation Mechanism March 13, 2022 0 0. The decay of the nuclear magnetization along a spin-locking field in the rotating frame has been studied in solid deuterium, at a frequency of 4.7 MHz, following the method of Rowland and Fradin. Measurements were made between 4 and 13 K, on samples having para (J=1) mole fractions X ranging from 0.04 to 0.9. The lab-frame transverse relaxation time T2 was measured in the range 13-17 K.

Abstract This article attempts to explain what nuclear relaxation is, why it can be a friend, why it can also be a foe, and how the destructive qualities of relaxation may sometimes be held at bay using the symmetry properties of the quantum states and of the relaxation processes.
