摘要：
The electric-field-induced reorientation of (s)-4-methylhexyl-4-[4-(decyloxy)phenylethynyl]-2-fluorobenzoate in the chiral smectic C (Sc*) phase under various conditions have been studied by time-resolved FT-IR spectroscopy. The time-resolved spectra reveal that the reorientation occurs immediately after the electric field is applied. Of particular note is that the C=O stretching band, strong in the IR spectra, is very weak in the time resolved difference spectra.
