Abstract

Lattice dynamics in bis-(n-C₁₆H₃₇NH ₃)SnCl₆, where the hydrocarbon part is analogous to lipid membrane, was investigated by means of 200 MHz ¹H nuclear magnetic resonance. As a result, critical fluctuations and molecular dynamics associated with the phase transitions, an order-disorder and a conformational phase transition, were distinguished in a wide temperature range. The dynamical origin of the critical fluctuations, observed in the long-chain compounds but not in the short-chain compounds, by the laboratory frame spin-lattice relaxation measurements, is revealed and discussed in this work.
