A sharp increase of the rotatory power in the isotropic phase of cholesteric liquid crystals is observed near the isotropic-cholesteric liquid transition. This is interpreted as a manifestation of short-range chiral orientational order in the isotropic liquid. An application of the Landau-de Gennes theory predicts a (T-T*)^-1/2 temperature dependence, in agreement with measured data in the immediate pretransition region.
