Multilayer structures form a particular class of samples employed in nuclea
r resonant scattering of synchrotron radiation. Their specific properties l
ead to unusual energy and time characteristics of nuclear resonant scatteri
ng, which differ much from those of single crystals. The analysis of these
distinctions is presented. Several approaches to achieve pure nuclear refle
ctions with multilayers are discussed. Finally, we review the studies of mu
ltilayer structures with nuclear resonant scattering of synchrotron radiati
on.
