Micellization of alkylated 1.4-diazabicyclo[2.2.2]octane by nuclear magnetic resonance technique using pulsed gradient of static magnetic field

► Micellization of 4-aza-1-tetradecyl-1-azoniabicyclo[2.2.2]octane bromide is shown. ► Concentration dependence of self-diffusion coefficients of molecules is given. ► Good agreement is observed between CMCs obtained in NMR and fluorimetry studies. ► Micellar radius and aggregation number increased with surfactant concentration. ► The role of external and internal translational diffusion of molecules is compared.
