Abstract
Pulse radiolysis studies of VK1 were carried out in a nitrogen-saturat ed aqueous-isopropanol-acetone mixed solvent. We studied the spectrosc opic characteristics of semiquinone radicals of VK1 and determined the kinetic parameters of formation and decay of the species. It was foun d that the decay process of semiquinone radicals of VK1 was according to a first-order reaction, this was different from the case in ethanol solution, possible reasons were also analyzed.
