パルスラジオリシス法により水溶液中のBr$$_{2}$$$$^{-.}$$とBr$$_{3}$$$$^{-}$$の吸収スペクトルを室温から350度の温度領域で測定した。同時にBr$$^{-}$$の吸収スペクトルも測定した結果、Br$$^{-}$$はCTTSバンドであるのに対し、Br$$_{2}$$$$^{-.}$$とBr$$_{3}$$$$^{-}$$はそうでないことが判明した。

The absorption spectra of Br$$_{2}$$$$^{-.}$$ and Br$$_{3}$$$$^{-}$$ in aqueous solutions are investigated by pulse radiolysis techniques from room temperature to 380 and 350 $$^{circ}$$C, respectively. Temperature dependent spectrum of Br$$^{-}$$ is also measured under steady-sate. If the absorption of Br$$^{-}$$ is of Charge Transfer To Solvent (CTTS), those of Br$$_{2}$$$$^{-.}$$ and Br$$_{3}$$$$^{-}$$ are not.
