A study of the kinetics of reorientation of a uniaxially aligned nematic liquid crystal (4-pentyl-4'-cyanobiphenyl) under the influence of an external ac electric field is reported. Step-scan FT-IR was employed for the acquisition of the dynamic linear dichroism spectra. 2D FT-IR frequency correlat
