Absorption spectra of poly [4, 4'-oxydiphenylene-pyromellitimide] (PMDA-ODA) molecule films with the exposure to polarized UV radiation were studied with polarized light in the UV-VUV and IR regions. Remarkable peaks were found at about in 4.4eV, 5.5eV and 6.5eV in the UV-VUV spectrum and at 1244cm^<-1>, 1377cm^<-1>, 1500cm^<-1> and 1723cm^1 in the IR spectrum. The intensity of peaks decreased by irradiation of UV light. Decreasing ratios of peaks were proportional to exposure energy and two types decreasing rations of peaks were found. For analysis these spectra, calculation of model compound with polyimide (PMDA/ODA) site was performed. Energy levels and DOS spectra were estimated and this result showed good agreement with decreasing ratios of peaks in the UV-VUV spectra.
