| Abstract: | Electron spin resonance spectra of free radicals formed in the radiolysis of benzen-2,1-diazoquinone-4-sulphonic acid in polycrystalline form have been recorded. Two different radical species were found; the first one was stable at 77 K, whereas the second one was formed at higher temperatures. The thermal stability of the latter was investigated in the 20–100 °C temperature range, and the kinetic parameters for the decomposition process were determined. An appropriate mechanism of radiolysis was proposed. |
