NMR Imaging and Volume-Selective Spectroscopy in Solids: Product Operator Formalism and Test Experiments
The goal is to develop techniques for imaging or localized determination of wide-line parameters of solid materials. An example is the local chain orientation of polymer materials. In a previous paper (1) we have combined the Jeener-Broekaert pulse sequence (2) for the production of dipolar order with phase-encoding NMR imaging (JEPHI). The dipolar order state was used to store the phase-encoded spatial information. We now report a general treatment of three-pulse sequences by the aid of a product operator formalism suitable for strong coupling of two-spin (1/2) spin systems (3). The aim is to generalize the imaging procedure and to define the optimal pulse parameters. We also report on a technique for image-guided localized solid-state NMR spectroscopy (4).
