| Outline of Final Research Achievements |
Solid state NMR spectroscopy of deuterium nuclei is an indispensable tool for investigating static and dynamic molecular structures of solid materials. Most of deuterium NMR, however, has been applied for diamagnetic solids, because in paramagnetic solids the magnetization suffers from the paramagnetic interaction that affects the measurement and analysis of spectra.
In the present work, we developed two solid-state deuterium NMR methods for paramagnetic solids. One is a method for separating chemically different sites by utilizing molecular dynamics, and the other is a separation method of nuclear interactions in two-dimensional NMR. Using these methods, we can investigate static and dynamic local structures about deuterium nuclei with increased accuracy.
