Paper Abstract

The IR spectra of wool fibers15 -irradiated in mixtures of two organic solvents were record- ed. The analysis of the spectra showed that irradiation of wool fibers in the presence of certain mix- tures results in the appearance of an absorption band at 1725 cm -1 corresponding to the absorp- tion of the carbonyl groups. The intensity of the COO - band at 1400 cm -1 is influenced by thenature of the solvents and the concentration of each solvent in the mixture. This band disappearswhen the fibers are irradiated in the presence of ethylalcohol and shows the intense absorptionwhen the fibers are irradiated in carbon tetrachloride. The intensities of the absorption bands in theregion 1000-1200 cm -1 vary also according to the nature of the solvents. Furthermore, the absor- bances of the amide I and aro ide II bands were determined. Ii was found that the induced changesin the absorbances of these bands depend on the dipole moment of the solvents.
