Fluorescence data-emission intensities and decay profiles of benzyl 1-pyrenoate in the presence of dimethylaniline in anionic homomicelles and in mixed micelles have been analyzed with two different models: a kinetic model of diffusion-controlled reactions in micelles with a reflecting boundary surf

✦ Synopsis
Ihe rate of dlffusional encounters betaeen two species confined painvise in small spherical volumes is imestigated by mezms of compu:er simulation and approximate analytical analysis. Such sysiems consisting of cage type subsystems uith two reactants occur in the case of micekr solubilized partners of a diffusion-conuoUed reaction_ It is shown that the rare of encounter or reaction is, to a good approCmation. that of a homogeneous solurion reaction where one molecule per
