摘要：Abstract {FTIR} spectroscopy has been in use broadly to study microscopic areas in polymers for the last years. The {FTIR} transmission spectra of coumarin laser dye, polystyrene and coumarin doped polystyrene films with different doping ratio of coumarin solution have been studied. These spectra measured and explained for all films before and after Alpha irradiation with different irradiation times. All samples prepared by casting method. {FTIR} corroborate chemical bonds of coumarin dye molecules and polystyrene films by producing an {IR} absorption spectrum when increasing doping ratio of coumarin solution and when irradiation by Alpha source. There are some bonds disappeared after irradiation.
