Comments on the published article “The effect of optical purity on the coexistence phenomenon and on the polarization - electric field hysteresis behavior in SmC* and SmC*A phases” by M. Chemingui et al., Journal of Molecular Liquids, 222 (2016) 1101-1108

This letter concerns error in assumed theoretical model and incorrect interpretation and presentation of experimental data in the article by M. Chemingui et al., “The effect of optical purity on the coexistence phenomenon and on the polarization - electric field hysteresis behavior in SmC* and SmC*A phases”, Journal of Molecular Liquids, 222 (2016) 1101-1108.
