We study the direct incoherent energy transfer in systems, in which th
e molecules involved in the transfer process are attached to ideal (Ga
ussian) polymers, randomly arranged in a viscous solvent. In what the
molecules' attachment to polymers is concerned we consider two differe
nt situations: (a) each polymer chain contains at its opposite ends a
donor and an acceptor molecule, (b) the donor molecules are dispersed
randomly in the solvent and all acceptors are attached to polymers, In
both cases we derive the donors' decay forms exactly. (C) 1995 Americ
