INTERMOLECULAR ORDERING OF HYDROGEN-BONDED LIQUID GLYCEROL

Analysis of X-ray diffraction data on trihydric H-bonded liquid glycer ol shows that at room temperature on the average each glycerol monomer has 6.5 hydroxyl neighbors at a distance of 2.95 Angstrom. The compar ison of intermolecular X-ray and neutron pair correlation function cur ves and the number of H-bonds per monomer suggests the possibility of parallel orientational correlation among the neighboring molecules and the combined analyses via X-ray and neutron data show that this possi bility is not ruled out.
