Raman spectra of ferroelectric liquid crystal (FLC) D-4-(2-methylbutoxy) phenyl 4-decyloxybenzoate (MBOPDOB) are recorded. All the vibrational modes are assigned, and their vibrational characteristics are studied. It is found that the s-cis and the s-trans conformers of the ester group coexist in the crystal phase at room temperature. By temperature-dependent measurements, the line shape changes due to the transition of the ester group conformation near the crystal-Sm C* phase transition point are examined.
