Rotating-frame nuclear magnetic relaxation in a long-chain model biomembrane (C 18H 37NH 3) 2SnCl 6

Research output: Contribution to journalArticlepeer-review


The lattice dynamics in bis-(n-(C 18H 37NH 3) 2SnCl 6, where the hydrocarbon part is analogous to a lipid membrane, was investigated by means of 55-kHz 1H rotating-frame nuclear magnetic resonance. The critical fluctuation near the order-disorder transition of the rigid alkyl chains is attributed to the high-frequency dynamics for long-chain compounds, in contrast to the low-frequency dynamics for short-chain compounds. Besides, the non-exponential spin-lattice relaxation is ascribed to chain segmental motions, giving rise to a distribution of correlation times and freezing below 230 K.
