Reaction behaviors of radiolysis products in mixtures of different ionic liquids containing thiocyanate anion were studied by measuring the transient absorptions under irradiation of electron pulses. Dimer radical ion of thiocyanate in the visible range and electron in the near-infrared range were observed in the ns-pulse radiolysis to measure their yields and reactions. The formations of products increased with increasing the thiocyanate concentration, regardless of kinds of cations in the mixture. The products were also observed in the ps-pulse radiolysis to clarify their formation pathways.
