Picosecond electronic energy-transfer studies in sodium dodecyl sulfate micelles

Abstract

Electronic energy-transfer between several pairs of extrinsic organic probes incorporated in SDS micelles was studied in the picosecond domain by following the donor fluorescence decay. Deviations to kinetic models where independent spatial distribution is assumed for donor and acceptor are attributed to probe induced perturbations of the micellar structure that result in an attractively correlated spatial distribution for the donoracceptor pair.
