The chemical modifications in bisphenol A polycarbonate induced by swift heavy ion irradiation are analyzed in situ by means of Fourier transform infrared (FTIR) spectroscopy. Four beams (C-13, Ne-20, Ca-48, Xe-129) with energy of a few MeV/amu have been used. Irradiations were performed under vacuum with electronic stopping power in the range from 1.6 to 86 MeV mg(-1) cm(2). Deposited doses are less than or equal to 1 MGy. The FTIR spectra obtained after the irradiation exhibit an overall reduction of the intensities of the virgin PC typical vibration bands and the appearance of new bands. The analysis of the destruction and the new vibration bands points out that the energy deposition mechanisms are quite different depending on electronic stopping power. (C) 2002 Elsevier B.V.
