The dynamic structure of Aerosol OT molecules in micellar state was studied by measurements of <SUP>13</SUP>C-NMR spin-lattice relaxation time (<I>T</I><SUB>1</SUB>) and the effect of a lantanide shift reagent Yb(fod)<SUB>3</SUB> in chloroform at 25 MHz and 40°C. The results were analyzed on the basis of the conformation and segmental motions of Aerosol OT molecules in micellar state, with the following conclusions: Aerosol OT molecules in the micellar state associate with each other by the polar head groups; their hydrocarbon chains are flexible; the mobility of side chain is restricted to a greater extent than that of the main chain; carbonyl carbon-(2′) is located nearer to the polar group than carbon-(2) in steric conformation.
