Abstract
Proton NMR was employed as a probe for the collective hydrocarbon chain dyn amics in decylammonium chloride (C10H21NH3Cl), a model biomembrane undergoi ng an irreversible structural phase transition sequence. Our rotating frame spin-lattice relaxation measurements revealed a low-frequency critical col lective chain dynamics in the kHz regime, which is associated with the inte rdigitated to noninterdigitated chain configurational phase transition.
