Intermicellar Material Exchange and Droplet Clustering in AOT Reverse Micellar Systems. A Pulse Radiolysis Study of (SCN)2 •- Radical Anion Spectra and Decay

The recombination of (SCN)2 •- radical anions has been used as an indicator reaction to study material exchange between reverse micelles of AOT in different hydrocarbons. The (SCN)2 •- radical anions were radiolytically produced in the reaction of OH• radicals with thiocyanate anions contained in the water droplets. The obtained data, both spectral and kinetic, are discussed in terms of interdroplet and intercluster reactant exchange. The average number of droplets per cluster seems to be significantly greater for AOT reverse micelles in n-heptane than in isooctane.
