Abstract
Near edge X-ray absorption fine structure (NEXAFS) spectra were obtained using synchrotron radiation for
polyfbutylene terephthalate) (FBT), UV-inadiated PBT, and 4,4'-biphenyldicartsoxylic acid dimethyl ester (PAM), which is a
model compound of FBT. The spectrum of PBT were mterpreted-with the comparison of the polarized NEXAFS spectra of an
oriented film of PAM. The polarization dependence of the peak previously assigned to 3p / rydberg state suggested its o-*
nature. The spectra of PBT drastically changed by UV irradiation, mdicating that chemical species Eke benzaMehyde were
formed on the PBT surface. These results demonstrate that NEXAFS spectroscopy is very useful also in the field of surface
photochemistry.
