The nature of the deviations from the mean-field approximation for the orientational susceptibility of the isotropic phase of a liquid crystal is related to the existence and proximity of a smectic phase. The observed effects can be described at a quantitative level by a theory incorporating the interaction of two order parameters: orientational (nematic) and translational (smectic).
