For two-component relaxation behaviour the time constant (apparent relaxation time) and the preexponential factor (apparent probability) of each of the components are complicated functions of the real relaxation times, the population fractions (real probabilities) and the lifetimes referring to two regions, between which an exchange of molecules, nuclei or spins occurs. The theoretical treatment of Zimmerman and Brittin is sketched and the apparent quantities as functions of the real quantities and vice versa are plotted in detail.
