✦ Synopsis

An analysis is presented of excimer formation of molecules solubllized in mice&r surfactant solutions. This treatment takes account of both the statistical distriiution of solubihzate molecules among the mice&s and the kinetic factors affecting excimer formation. By using this analysis to interpret the results of steadystate fluorescence-intensity measurements, where the excimer and monomer emissions of pyrene solubilized in a num.wzr of surfactants are m-red, it is possible to gaininformation about mice&r size and about the mobility and disposition of pyrene molecules within the micelle.

This paper describes the influence of counterions on the unidirectional growth of micelles formed by alkylpyridinium surfactants in aqueous solution. It is shown that the growth of spherical micelles to form wormlike micelles is strongly dependent on counterion structure. More hydrophobic counterion
