We report chemical damage to the methine (CH) and methylene (CH₂) groups in poly(allyl diglycol carbonate) (PADC), which is a polymeric nuclear track detector, under gamma rays and heavy ions (C and Kr) using Fourier Transform Infrared (FT-IR) analysis. By comparing the IR spectrum of PADC from 2700 to 3100 cm⁻¹ to that of diethyleneglycol bis allylcarbonate (ADC), which is a monomer of PADC, we found that the peak at 2920 cm⁻¹ was assigned to the methine group at the three-way junction. The methine group was barely damaged by gamma rays and heavy ions. It is necessary that at least two tracks interact with a single PADC unit to damage the methine group.

我们报告了使用傅立叶变换在伽马射线和重离子（C 和 Kr）下聚（烯丙基二甘醇碳酸酯）（PADC）中的次甲基（CH）和亚甲基（CH ₂）基团的化学损伤红外 (FT-IR) 分析。通过将 PADC 2700 至 3100 cm ^-1的红外光谱与作为 PADC单体的二甘醇双烯丙基碳酸酯 (ADC)的红外光谱进行比较，我们发现 2920 cm ^-1处的峰归属于三个-路交界处。次甲基几乎没有被伽马射线和重离子损坏。必须至少有两条轨道与单个 PADC 单元相互作用才能损坏次甲基。
