During nuclear magnetic resonance observations, spin–lattice relaxation is the mechanism by which the longitudinal component of the total nuclear magnetic moment vector (parallel to the constant magnetic field) exponentially relaxes from a higher energy, non-equilibrium state to thermodynamic equilibrium with its surroundings (the "lattice").
The spin-lattice (or longitudinal) relaxation time T1 quantifies the rate of transfer of energy from the. nuclear spin system to the neighboring molecules (the lattice). This is relaxation in the z-direction and leads to restoration of Boltzmann equilibrium.

Jan 30, 2023 · T 1 relaxation, also known as spin lattice or longitudinal relaxation is the time constant used to describe when ~63% of the magnetization has recovered to equilibrium. The T 1 of a given spin is dictated by field fluctuations (both magnetic and electric) that occur in the sample.
Apr 8, 2023 · The T1 relaxation time, also known as the spin-lattice relaxation time or longitudinal relaxation time, is a measure of how quickly the net magnetization vector (NMV) recovers to its ground state in the direction of B 0. The return of excited nuclei from the high energy state to the low energy or ground state is associated with loss of energy ...
T1 relaxation, also known as spin-lattice relaxation, is the release of energy to the environment, or lattice, that results in the reestablishment of the magnetization along the Z axis. Thus T1 is the time constant by which the longitudinal (or Z) magnetization relaxes to its equilibrium value, M0.
Nuclear Spin Relaxation. In NMR, a strong magnetic field is used to partially polarize the nuclear spins. Taking protons as the most common example, the excess of proton spin in the direction of the magnetic field constitutes a small net magnetization of the material. To set up the conditions for the observation of an NMR signal, strong radio ...
Spin-Lattice Relaxation. Spin–lattice relaxation is caused by magnetic interactions that make pairs of neighboring nuclei change their spin orientations simultaneously. From: Comprehensive Natural Products Chemistry, 1999
