Spin locking and spin–lattice relaxation in a liquid entrapped in nanosized cavities
Abstract
We study the dynamics of the nuclear spins in a liquid entrapped in nanosized cavities. This spin system is like a solid system where all the spins are coupled equally with the same interaction constant. It is shown that, under the high temperature approximation, the system is described by the two-temperature quasi-equilibrium density , and is proportional to the concentration of the molecules, C. The spin–lattice relaxation rates, 1/T1ρ and 1/T1d, are proportional to C2/N. An
