The reactions of Br2 '- anion radicals with thiocyanate anions in the ionic liquid methyltributylammonium bis[(trifluoromethyl)sulfonyl]imide (R4NNTf2) were studied by pulse radiolysis. Reaction of solvated electrons with BrCH2CH2Br (DBE), k = (1 2)×108 L.mol 1.s 1, leads to the production of Br2'- anion radicals. The intermediate absorption spectra following pulse radiolysis of DBE/SCN-/Br-/ solutions in R4NNTf2 correspond to Br2 '-, BrSCNo- and (SCN)2'- anion radicals. The participation of these radicals in the spectra changes with progressing reactions and depends on the concentration Br- and SCN- in the solution.

A new control and measurement system for a pulse radiolysis setup based on the linear electron accelerator LAE 13/9 is described. It consists of CAMAC apparatus, two oscilloscopes: Tektronix TDS620 and Iwatsu TS8123, and a PC computer as a central unit for programming and controlling of the experiments and for results processing. The program is written using DELPHI 1.0 (Borland) programming platform and it can operate in WINDOWS 3.x or WINDOWS 95 environment.

Opisano nowy system kontrolno - pomiarowy do radiolizy impulsowej opartej na liniowym akceleratorze elektronów LAE 13/9 Żerań. W jego skład wchodzą: aparatura systemu CAMAC, dwa oscyloskopy - Tektronix TDS620 i Iwatsu TS8123, komputer PC jako centralna jednostka do programowania i kontrolowania eksperymentów oraz przeliczania wyników. Program jest napisany przy użyciu pakietu DELPHI 1.0 (Borland) i jest przystosowany do środowiska WINDOWS 3.x i WINDOWS 95.
