Abstract
Abstract A phenomenon of micellization of 4-aza-1-tetradecyl-1-azoniabicyclo[2.2.2]octane bromide (AB-14) in aqueous solution has been studied by the methods of nuclear magnetic resonance using magnetic field pulse gradient and fluorimetry. The critical micelle concentration is determined; concentration dependences of percentage of free AB-14 molecules and those associated with micelles as well as radii of micelles and numbers of their aggregation are established. Effect of external and internal translational diffusion of molecules on lifetime of AB-14 molecules in micelles is investigated.
