(a) Ultralene FTIR absorbance spectra at different exposure doses from Rad0 (lighter red colour, at the bottom) to Rad4 (darker red colour, at the top). Spectra are displayed with an offset of 0.3 a.u. (arbitary units) for clarity. Characteristic bands are highlighted with grey lines for further reference: 3420 cm−1 (only at Rad4), 2960, 2920, 2870, 2839, 2722, 1710 (only at Rad4), 1457, 1378, 1359, 1326, 1303, 1254, 1168, 1103, 1043, 996, 973 cm−1 (from left to right). (b) Close-up of the ultralene FTIR absorbance spectrum in the range 1180–1140 cm−1. Bands highlighted with grey lines indicate the component at ∼1166 and at ∼1155 cm−1. (c) Paraffin on ultralene FTIR absorbance spectra at different exposure doses from Rad0 (at the bottom) to Rad4 (at the top). Spectra are displayed with an offset of 2.0 a.u. for clarity. (d) Close-up of the paraffin supported on ultralene FTIR absorbance spectrum in the range 1180–1140 cm−1.
