The collective hydrocarbon chain dynamics in decylammonium chloride (ClOCl) was analyzed using proton nuclear magnetic resonance measurements. The phase transition sequence of ClOCl was verified using differential scanning calorimetry while the impurity of the sample was checked by the elemental analysis (EA), X-ray fluorescence (XRF) and infrared (IR) measurements. The results show that the rotating frame spin-lattice relaxation time representing the ultraslow hydrocarbon chain motions shows a critical divergence which is attributed to the interdigitated to non-interdigitated chain configurational phase transition of the lipid bilayers.
