Data acquisition and analysis of broad chemical-shift powder patterns from solids with spin-echo techniques

The data acquisition and processing of the wide‐line chemical‐shift NMR spectra of solids present unique challenges. Developing procedures to minimize and address inherent distortions is critical for the proper determination of NMR chemical‐shift parameters from these wide‐line spectra. The analysis of such data provides an understanding of many assumptions that are made about solids and liquids in spectroscopy. We discuss techniques for the analysis of spin–echo spectra broadened by chemical‐shift dispersion. © 2002 Wiley Periodicals, Inc. Concepts Magn Reson 14: 365–387, 2002
