[en] Transient species in the radiolysis of CFCl³ and CBrCl³ was studied by stroboscopic picosecond pulse radiolysis. Two principal bands in the UV and Vis region were observed in both samples and identified as cations and charge transfer complexes of parent cations and halogen anions respectively. (author)

[en] Transient cationic species produced in irradiated liquid n-alkanes (heptane-decane) were observed by the stroboscopic picosecond pulse radiolysis technique at room temperature. The half life, buildup spectra and G epsilon were obtained and discussed. (author)

[en] Direct measurements of the yield of hydrated electrons in aqueous solutions and solvated electrons in alcohols were carried out using a stroboscopic picosecond pulse radiolysis system. The yield of solvated electrons was obtained by simultaneous consideration of the pulse shape and radiation doses. The yield at 30 ps after irradiation, G(esub(aq)^-)sub(30ps), was determined to be 4.8 +- 0.3 products per 100 eV as compared to the G(esub(aq)^-)sub(100ns) of 2.7. Experimental values, including the present ones, are higher by 0.3 than the theoretical ones calculated using the spur diffusion model in the time period from 3 x 10^-11 to 10^-8 s. Nevertheless, both results show a quite similar time dependence, i.e., fast decay of hydrated electrons in spur reactions. The G-values of solvated electrons at 30 ps were also determined in alcohols. The G-value of solvated electron is 3.4 +- 0.3 in both methanol and ethanol, 2.0 +- 0.3 in 1-propanol and 2.3 +- 0.3 in ethylene glycol. (author)

[en] Transient species produced in neat butylchloride and butylbromide were observed by means of picosecond pulse radiolysis. The visible band which was produced during electron pulse and then decayed with a half lifetime of 2 ns was assigned to a vibrationally excited cation. (author)

[en] Transient species produced in neat butychloride, butylbromide and butyliodide were observed by means of picosecond pulse radiolysis using 11 ns pulses of 45 MeV electrons. The visible band which was produced during electron pulse and then decayed with a half lifetime of 2 ns was assigned to a vibrationally excited cation. (author)
