Abstract
Detailed X-ray diffraction studies of bis-(4'-n-heptyloxybenzylidene)-1,4-phenylenediamine (HEPTOBPD) have led to a positive phase identification, subsequently given confirmation by texture and miscibility studies. No new smectic liquid crystal phases, but two disordered crystal phases (J and K) are found which are analogous to G and H phases except for the direction of tilt.Keywords
