摘要：

By use of submicrosecond multichannel asynchronous time-resolved FT-IR spectroscopy, we have investigated a time-dependent response of different molecular segments during dynamical switching in the electric-field-induced phase of a ferroelectric liquid crystal (FLC) with a naphthalene ring (FLC-1). From measurements of temporal response of absorption changes of infrared (IR) bands at different time delays, we demonstrate that two carbonyl groups of FLC-1 respond first on switching the electric field and then the alkyl chain and the mesogen follow.
