spin-lattice relaxation

Furthermore, nuclear spin-lattice relaxation rates depend on local molecular mobility.

The spin-lattice relaxation time can be measured with an inversion recovery experiment.

The spin-lattice relaxation results from the urge of the system to return to thermal equilibrium after it has been perturbed by the B pulse.

Return of the magnetization parallel to B is achieved through interactions with the surroundings, that is spin-lattice relaxation.

The fact that T relaxation involves an interaction with the surroundings is the origin of the alternative description, spin-lattice relaxation.

It is characterized by the spin-lattice relaxation time, a time constant known as T. It is named in contrast to T, the spin-spin relaxation time.

This affects the lineshape of the resonance and its temperature dependence and allows probing the spin-lattice relaxation differently in EPR and APR.

The name spin-lattice relaxation refers to the process in which the spins give the energy they obtained from the RF pulse back to the surrounding lattice, thereby restoring their equilibrium state.

They use the Nuclear Overhauser effect (NOE) by which nearby atoms (within about 5 Å) undergo cross relaxation by a mechanism related to spin-lattice relaxation.

Only small amounts of shift reagents are used, because otherwise the paramagnetism of the reagent shortens the spin-lattice relaxation times of the nuclei, which causes uncertainty broadening and loss of resolution.

Spin-lattice relaxation is the mechanism by which the z component of the magnetization vector comes into thermodynamic equilibrium with its surroundings (the "lattice") in nuclear magnetic resonance and magnetic resonance imaging.

The unique charge characteristic of this complex allows researchers to inversely measure spin-lattice relaxation times as they are related to the concentration of proteoglycan aggregates and charged glycosaminoglycan side chains in articular cartilage.

Delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the Spin-lattice relaxation time or T1 relaxation time.

A primary focus of the research in the Bryant laboratory is of information obtainable from the magnetic relaxation dispersions (MRD) or from the magnetic field dependence of the nuclear spin-lattice relaxation rate as a function of the magnetic field strength.

Dynamic properties such as duplex-single strand equilibria and binding rates of other molecules to duplexes can also be determined by its effect on the spin-lattice relaxation time T, but these methods are insensitive to intermediate rates of 10-10 s, which must be investigated with other methods such as solid-state NMR.
