NMR spectroscopy and applications

The quadrupole coupling constant CQ and the electric field asymmetry parameter η were determined directly from the dispersive mode NMR lineshape of the 11B resonance in borate glass. Simple relationships allow for the calculation of CQ and η from the locations of the quadrupolar satellites and shoulders. These locations are found from the zero crossing points of the second and third derivatives of the dispersive lineshape. This method lends itself to an analysis of the experimental error. For 11B in borate glass, CQ and η are found to be 2.670 ± 0.038 MHz and 0.107 ± 0.008, respectively.
