The orientation dynamics of a ferroelectric liquid crystal with a naphthalene ring (FLC-2) and without a transverse dipole in chiral moiety during the electric-field-induced switching was investigated by time-resolved infrared (IR) spectroscopy combined with normalized sample-sample two-dimensional correlation spectroscopy. It was found from the present study that the reorientation track of the core at the positive half period is different from the negative half period, while the reorientation track of the C=O dipole moment and the alkyl chains at the positive and negative half period is very alike during the electric-field-induced switching.
