|Abstract:||High pressure, Xray and miscibility studies on binary mixtures of terminally substituted cyano and nitro compounds have led to the observation of two kinds of A-A transitions, viz., Ad-Ad and Ad-A1, the former being observed for the first time. The signatures of these transitions, which are not observable either optically or by differential scanning calorimetry, are seen dramatically in the smectic A -nematic phase boundary in the P-T plane. Xray results show that the Ad-Ad transition is from a partially bilayer smectic A with a temperature-independent layer spacing to one with a temperature-dependent layer spacing.|
