Low-temperature (77 K) γ- and UV irradiation of substituted N′-furfurylidenebenzhydrazides produces paramagnetic particles in radiation-chemical yields of (0.05-0.5)/100 eV and quantum yields of 4 · 10-5-10-3, respectively. ESR study showed that hydrazyl radicals and HC- O and N -O2 are the main products of radiolysis and photolysis, and the latter decay upon heating of the sample to 190 K, whereas the hydrazyl radicals survive up to 423 K. Further heating results in thermodestruction of the hydrazides, and the ESR spectrum exhibits only a singlet with splitting at 1 mT, which is characteristic of polyconjugated compounds.
