Abstract
The infrared spectra of polypyrrole contacting with T2O gas were observed for ca. 100 days. After adding T2O (1.2 Ci; isotopic purity: 15%) the band at 2180 cm−1 was observed, which is assigned to the N–T stretch. Although the bands at 1560 and 1204 cm−1 were initially strong, they became relatively weak by T β-irradiation. On the other hand, the bands at 1655 and 1400 cm−1 as well as 1700 cm−1 became relatively strong by T β- irradiation. These are explained in terms that the quinonoid-type structure with partially the aromatic-type structure decreases and the structure with probably C = N bonds is formed. It was also found that many carbony defects are formed in both the atmosphere and T β-radiolysis.
