N2 - The pulse radiolysis method is used to study the optical absorption spectra in azeotropic sulfuric acid at 298 and 373 K. The spectra showing maximum absorption at 460 and 275 nm, observed at 298 K in the acid saturated with N2, are associated with the radicals of HSO4 and HSO3, respectively. An additional absorption band of HSO5 radical having a maximum at 245 nm appears in the acid saturated with O2 at 298 K and in the acid saturated with N2 at 373 K. It is suggested that the short-lived (under 1 μs) absorption bands with the maximums at ca 380 and 290nm belong to the transient species H2SO-4 and H2SO+4, respectively. The obtained results are used to construct the machanism of the early stages of the low- and high-temperature radiolysis of concentrated sulfuric acid.
