Exciton traps in molecular crystals at low temperature are discussed for three types: chemical traps formed by fareign molecules, physical traps formed by structural disturbance of the host or pure crystal and self-traps. Self-traps are redefΓ―ned in terms of intra-and Γ―ntermolecular processes which
