Microcrystallites, Mossbauer spectrum

Mossbauer spectroscopy of the iron salt showed two different iron environments one having a high water content and the other with almost no assodated water molecules. Quasi-elastic neutron scattering revealed that there were two types of water molecule, each with different diffusion coefficients, which were observed in the quasi-elastic spectrum as peaks having different widths. To explain these observations the authors presented a structure containing three phases microcrystallites, ionic clusters, and an intermediate ionic phase with a lower ionic concentration. The relative proportions of the last two phases depended on the...
