Abstract
The malachite green leucocyanide (MGCN) was irradiated in argon or oxygen saturated solutions of n-butyl chloride, 1.2-DCE, CCl/sub 4/ and acetone with 13 ns electron pulses. Two species with absorption maxima at 620 and 480 nm were observed. The latter was attributed to the malachite green leucocyanide radical cation (MGCN/sup +radical/) and the former to the known carbonium ion of malachite green dye (MG/sup +/). Observation of the consecutive charge transfer via the schemes: DCE/sup +radical/ -> BPh/sup +radical/ -> MGCN/sup +radical/ and DCE/sup +radical/ -> MGCN/sup +radical/ -> TMPD/sup +radical/, allowed to estimate the ionization potential of MGCN molecule in the range 6.9 eV < Ip/sub MGCN/ < 8.27 eV. Presented results and literature data suggest that positive charge in MGCN/sup +radical/ radical cation is located in the ''aniline'' part of the molecule. (author).
