| الوصف: | Neutron powder diffraction has been used to observe the changes in hydrogen bonding that occur as a function of temperature in ND4IO3, and thus determine the structural features that occur during the low temperature (103 K) phase transition. We show that in the deuterated material the change is not a phase change per se but rather a structural reorganization in which the hydrogen bonding becomes “firmly locked in” at the phase transition temperature, and stays in this configuration upon further cooling to 4.2 K. In addition, both the differences and changes in the axial thermal expansion coefficients in the region 100 – 290K can be explained by the changes involving both the hydrogen bonding and secondary I---O halogen bonds. |
