One process, called T1, is responsible for the loss of resonance intensity following pulse excitation. The other process, called T2, characterizes the width or broadness of resonances.

Jun 29, 2020 · The process by which the magnetization in the xy plane decays away, over time, to its equilibrium value of zero, is known as T2 relaxation, transversal relaxation, relaxation on …

T2 relaxation is the process by which the transverse components of magnetization (Mxy) decay or dephase. As originally described by Felix Bloch (1946), T2 relaxation is considered to follow …

T2* can be considered an "observed" or "effective" T2, whereas the first T2 can be considered the "natural" or "true" T2 of the tissue being imaged. T2* is always less than or equal to T2. T2* …

In physics, the spin–spin relaxation is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value in nuclear …

Apr 25, 2022 · Because quantitative NMR measurements rely on resonance intensity, understanding the effects of T 1 relaxation is very important for obtaining accurate qNMR …

Aug 23, 2007 · • T2 relaxation – how long it takes for the spins to lose phase coherence, allowing the net magnetization (M 0) decay to 0 in the xy plane. – Spin flipping (+½ ↔-½) due to …

The major factor limiting determination of protein structure by NMR is the sensitivity as modulated by relaxation time. Hence determinationn of this parameter is a critical preliminary …

Transverse magnetization decay is described by an exponential curve, characterized by the time constant T2. After time T2, transverse magnetization has lost 63 % of its original value. T2 is …

Transfer relaxation corresponds to the loss of phase coherence or randomization of spins in transverse direction (x-y) direction, which causes the loss of transfer magnetization. T2 refers …
