T1 and T2 relaxation

In NMR, relaxation is the process by which magnetization returns to equilibrium. Relaxation is important because it determines how long to wait between scans, how quickly signals decay, and the width of peaks in a spectrum. In the vector model relaxation is separated into T1 relaxation along the z-axis and T2 relaxation in the x-y plane.
