The time taken for this relaxation is called the relaxation time, which includes two types, spin-lattice relaxation time (T1) and spin-spin relaxation time (T2).

Webtime characteristic of this return to thermal equilibrium magnetization is called a relaxation time. The TeachSpin PNMR can be used to measure two different quantities referred to as … WebRelaxation can occur as the so-called spin–lattice relaxation (also called longitudinal relaxation, characteristic time T1 ), which probes the fast-to-intermediate dynamics of a system of the mid-kHz to GHz scale, while the spin–spin relaxation (transverse, T2) probes slower processes.

WebThis relaxation process is described by the spin-lattice relaxation time T 1, which is a characteristic time needed by the magnetization to return to the z-axis, and by the spin-spin relaxation time T 2, which describes the vanishing time of the magnetization in the xy-plane.
