The local structure of P-rich and Se-rich phosphorus–selenium glasses was studied using high-resolution31P solid-state MAS NMR. Two-dimensional31P homonuclear through-bond correlation MAS experiments and 2D homonuclearJ-resolved MAS measurements were performed at high spinning frequency to probe P...

This is consistent with the fact that the solid-state 31P CP MAS NMR spectrum gives one set of principal values of the nuclear magnetic shielding tensor. Similar values were obtained for solvates of other aromatic compounds such as benzene, o-dichlorobenzene, methoxybenzene and p-dimethoxybenzene....
1H31P CP/MAS NMR spectra reveal one-bond J-couplings, 1J(65/63Cu, 31P), for all complexes, as well as the presence of residual dipolar coupling, which enables determinations of both the sign of CQ and the orientation of the EFG tensor with respect to the CuP dipolar vector (both of...
The31P NMR spectra of bone specimens showed a single line characteristic of bone calcium phosphate.13C cross-polarization (CP) MAS NMR spectra of bone exhibited the characteristic signatures of collagen type I with good resolution for all major amino acids in collagen. Quantitative measurements of...
Solid-state 31P and 13C magic angle spinning (MAS) NMR spectra were used to characterize pure bisphosphonates and also bisphosphonates adsorbed on hydroxyapatite. Four geminal bisphosphonates, including the clinically used compounds ethane-1-hydroxy-1,1-diphosphonic acid, 3-amino-1-hydroxypropane-1,...
