Crystalline state hierarchical structure

Up to this point, we have summarized the NMR parameters of some selected crystalline compounds. Model crystalline compounds of calcium phosphates are important structural reference for the study of biominerals because the highly complex hierarchical structures of bones and teeth contain different phosphorus species such as unprotonated orthophosphate (PC>43 ) and protonated orthophosphate (HP042 ).70,77 It is beyond doubt that 31P chemical shifts are the most important spectroscopic parameters for the characterization of calcium phosphates. While the 31P chemical shift can reflect the protonation state of a phosphate species, 31P CSA is a sensitive measure of the symmetry of the electronic... [Pg.24]
