Abstract
Investigation of the micellar characteristics of aqueous cetyltrimethylammonium bromide (CTAB), through the excited state proton transfer reaction of carbazole reports two critical micellar concentrations for the surfactant. Steady state as well as time-resolved studies establish that both the CMCs are affected in the presence of urea. Observation further revealed that urea disfavours the ESPT process in micellar solution. This has been interpreted in the light that urea expels the fluorescer molecule from the micellar surface to the bulk water.
