Effect of dioxane on the benzil:SDS radical pair system. A study in the presence of high magnetic fields

The magnetic response of the radical pair generated by the hydrogen abstraction of the photoexcited benzil triplet from sodium dodecyl sulphate is studied. It is found that radical decay curves, with or without magnetic field, are affected on addition of small amphiphiles such as 1,4-dioxane. The results have been interpreted on the basis of the ability of the latter to change the micellar aggregation number and intramicellar viscosity.
