Temperature dependence of the Spin-Lattice Relaxation Time
The spin-lattice relaxation time, TX, of the 2 3 N a N M R line in N a N 0 2 is measured between 25 K and 160 K at two magnetic field strengths, 1.1 T and 6.9 T. The temperature dependence of TX for the center line, observed on a polycrystalline sample prepared by precipitation from aqueous solution, is given by a monotonous curve. Tx increases gradually as the temperature decreases. On the oth...
متن کاملTemperature dependence of the anisotropy of the planar oxygen nuclear spin-lattice relaxation rate in YBa2Cu3Oy
We report measurements of the full planar O nuclear spin-lattice relaxation rate tensor in optimally and underdoped YBa 2Cu 3O y (y56.96 and 6.63). The anisotropy varies strongly with temperature in both samples: for the y56.63 sample, the ratio of the relaxation rate measured with the applied field in the ab plane and oriented parallel to the copper-oxygen bond axis to that measured with the a...
متن کاملStudy of NMR spin lattice relaxation of several aldehydes
The NMR spin lattice relaxation of various aldehydes has been investigated. The experimental values of NMR spin lattice relaxation time T1 of benzaldehyde, anisaldehyde, o-cholorobenzaldehyde and p-hydroxybenzaldehyde have been correlated with the calculated value of N M R spin lattice relaxation time T1 obtained using various equations for dielectric relaxation time τ. It has been concluded th...
متن کاملDependence of Saturation-Transfer EPR Intensities on Spin-Lattice Relaxation
The intensities of saturation-transfer EPR (ST-EPR) spectra from nitroxyl spin labels have proved a sensitive means for studying slow exchange processes (both Heisenberg spin exchange and physical/chemical exchange) and weak interactions with paramagnetic ions, via the dependence on the effective spin-lattice relaxation rate (D. Marsh, Appl. Magn. Reson. 3, 53, 1992). The dependences of the sec...
