Hole-burning experiments, the most demonstrative appearance of spectral inhomogeneity, prove the existence of a large number of independent homogeneous sub-systems in an inhomogeneously broadened system. The stretched exponential (Kohlrausch) relaxation is another quite general phenomena in amorphous matter, A new interpretation of Kohlrausch relaxation will be explained on the basis of independent parallel decays of these homogeneous sub-systems, and it is proven by the results of simulations.
