We report a study of the infrared, photoinduced absorption in GaAs/AlAs and GaAs/Al0.33Ga0.67As multiple quantum well structures. The two observed lines are due to the (e1 : hh1)-(e2 : hh1) intrinsic excitons and a transition of excitons bound to imperfections. The exciton transition energy, polarization, intensity and its dependence on the excitation intensity are discussed.
