Abstract
In NMR measurements, the nuclei that become excited by the irradiating RF field give up their surplus energy to their surroundings over a period of time to return to the equilibrium state. This process is called NMR relaxation, and involves longitudinal relaxation and transverse relaxation. The time constants of these relaxation processes, known as the spin-lattice relaxation time (T 1) and the spin-spin relaxation time (T 2), are important NMR parameters besides chemical shifts and spin-coupling constants. In this chapter the basic principles of NMR relaxation and its practical application to polymers are described. A detailed description of NMR relaxation and its application for general purposes are found in Refs. [1–7].
