Abstract:

The paper describes how neutron diffraction has been used to determine the complete structure of the room-temperature phase of NH4NO3 for the first time. This information alone has provided considerable insight into the role of water vapor in the physical instability of this substance. In addition, neutron spectroscopy has been applied to NaNO3 to obtain the first, reasonably complete description of the dynamics of molecules in any metal-nitrate salt and to discern the relation between dynamics and instability. In order to accomplish the latter work of significant advance in the theoretical interpretation of complex spectra was required and achieved. Author
