 Title    Salts of Phosphonic Acid Derivatives: Illustrative Examples of Solid State NMR Spectroscopy  
 Abstract    H igh-resolution solid state 1 3 C, 23Na and 31P N M R data have been obtained for the acid form and for several salts o f the phosphonic acids: eth an e-1 ,2 -diphosphonic acid, ethane-l-hydroxy-1.1-diphosphonic acid (H E D P), and 3-am ino-l-hydroxypropan e-l,l-d ip hosp hon ic acid. The data provide evidence by which sample purity and crystallinity may be exam ined and from which the size o f the asymmetric unit may be determ ined. In the case o f the sodium salts o f ethane-1.2-diphosphonic acid, the 3IP and _3Na spectra provide evidence o f possible motion or bond fluctionality for the phosphonic acid group.
