N2 - The pulse radiolysis of the zwitterion sulfonato-propyl-viologen (SPV) was studied in aqueous solutions containing 2-propanol. SPV reacts with the hydrated electron and the 2-propanol radical yielding the anion radical, SPV-. The absorbance changes due to the formation of SPV- were followed at 578 nm (ε{lunate}578 = 1.0 × 104 M-1 cm-1). In the absence of colloidal platinum (Ptc) or air, SPV- is stable for at least several hours. In the presence of Ptc a single decay process was observed. The results are compared with the nitrobenzene-Ptc and methylviologen-Ptc systems.
