Time-resolved infrared spectroscopy of ferroelectric liquid crystals

FT-IR time resolved spectroscopy (FT-IR TRS) with simultaneous temporal and spectral resolution has emerged as a powerful technique to elucidate dynamic, segmental information concerning both orientation and conformational changes of liquid crystalline molecules during the electric-field-induced reorientational transition. This paper describes the experimental setup for time-resolved measurements using a step-scan FT-IR spectrometer and reports the results of dynamic analysis of ferroelectric liquid crystals (FLC).
