- 論文の詳細を見る
We have studied molecular motions and the microscopic environment at the SmA-SmC (SmC^*) transition in a racemic (chiral) smectic liquid crystal by means of ^<13>C NMR with CP/MAS and without sample spinning. Fast overall fluctuation caused by the existence of the molecular chirality has been observed in the SmA phase by T_1 measurements. Static NMR spectra indicate that the conformation of the enantiomer in the SmC^* phase is different from that of the corresponding racemic compound in the SmC phase.
