The formation mechanism of DMSO–halogen atom complexes in the solution of DMSO and halocarbons has been investigated by pulse radiolysis method. Three formation processes have been found depending on the the solution component. In the case of DMSO/CCl<SUB>4</SUB> mixtures, the absorption band at 400 nm due to the complexes has been observed at any composition. In CCl<SUB>4</SUB> solutions, the complex is formed by the reaction of the chlorine atom with DMSO, while in DMSO solutions, the reaction between the parent radical cations of DMSO and Cl<SUP>−</SUP> is dominant. It is suggested that the contribution of direct excitation of the strongly interacted ground state DMSO–CCl<SUB>4</SUB> encounter pairs becomes more important with increasing CCl<SUB>4</SUB> concentration.
