Spectroscopy of a Gamma Irradiated Poly(Acrylic Acid)-Clotrimazole System

A poly(acrylic acid)-clotrimazole system, gamma irradiated at different doses, is investigated by Raman spectroscopy. Modifications of the spectrum of the polymeric matrix appear for doses of radiation greater than 333 Gy, whereas the spectrum of clotrimazole remains unaffected at these doses of radiation. These changes correlate with modification of the vibration modes of COOH and CH₂ groups of a polymeric matrix after irradiation.
