STRAFI imaging of paramagnetic solids: 31P paramagnetic displacements†‡
نویسندگان
چکیده
One-dimensional stray field (STRAFI) profiles of 31P in phantoms containing, variously, calcium hydroxyapatite, calcium orthophosphate and cobaltous phosphate octahydrate were obtained in a STRAFI field of 11.7 T on a 19.6 T magnet at 206 MHz. The intrinsic spatial resolution with the apatite and orthophosphate samples was about 100 μm. The profile of the image from the paramagnetic cobaltous sample was displaced to high field by 1.2 MHz. The spatial resolution for the cobalt component was degraded because of the large linewidth of ∼0.6 MHz. Copyright 2001 John Wiley & Sons, Ltd.

31P NMR Resonances of Methyl Phosphite and Methylethyl Phosphate Anions by Selected Metal Complexes
Methyl phosphite ((CH3O)P(H)(O)2; MeOPH) and methylethyl phosphate ((CH3O)P(OCH2CH3)(O)2; MEP) are two members of a class of anionic ligands whose 31P T2 relaxation rates are remarkably sensitive to paramagnetic metal ions. The temperature dependence of the 31P NMR line broadenings caused by the Mn(H2O)62+ ion and a water-soluble manganese(III) porphyrin (MnIIITMPyP5+) indicates that the extent...

متن کاملEnhanced sensitivity and resolution in (1)H solid-state NMR spectroscopy of paramagnetic complexes under very fast magic angle spinning.
High-resolution NMR spectroscopy for paramagnetic complexes in solids has been rarely performed because of its limited sensitivity and resolution due to large paramagnetic shifts and associated technical difficulties. The present study demonstrates that magic angle spinning (MAS) at speeds exceeding 20 kHz provides unusually high sensitivity and excellent resolution in 1H solid-state NMR (SSNMR...

Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...
