  • Quadrupolar nuclei NMR using residual dipolar splittings in solids
    Patent number: 7276903
    Abstract: A method for obtaining NMR (=nuclear magnetic resonance) spectra of quadrupolar nuclei having spin I>½ using magic angle spinning (=MAS) in solid powders and transfer of coherences from a neighboring nucleus with spin S= 1/2 to single- or double-quantum transitions of quadrupolar nuclei having spin I>½, is characterized in that the transfer of coherences occurs through a combination of scalar and residual dipolar splittings. With the inventive method improved NMR-spectra can be obtained from which parameters can be extracted, which can be related to the structure and internal dynamics of solids containing the quadrupolar nuclei.
    Type: Grant

  • Quadrupolar nuclei NMR using residual dipolar splittings in solids
    Publication number: 20070013373
    Abstract: A method for obtaining NMR (=nuclear magnetic resonance) spectra of quadrupolar nuclei having spin l>½ using magic angle spinning (=MAS) in solid powders and transfer of coherences from a neighboring nucleus with spin S= 1/2 to single- or double-quantum transitions of quadrupolar nuclei having spin l>½, is characterized in that the transfer of coherences occurs through a combination of scalar and residual dipolar splittings. With the inventive method improved NMR-spectra can be obtained from which parameters can be extracted, which can be related to the structure and internal dynamics of solids containing the quadrupolar nuclei.
