Abstract
The first two-dimensional 1H NMR image of a solid whose linewidth is not narrowed by motional averaging is presented. The image of a polyethylene phantom was acquired with line narrowing by multiple-pulse coherent averaging of the homonuclear dipolar broadening, and by magic-angle sample spinning of the chemical shift anisotropy. To obtain the image, a magnetic field gradient was rotated synchronously with the spinner, and a series of spectra were recorded at incremented phase differences between the spinner and the magnetic field gradient. An image was calculated from these spectra by the filtered back projection method.
