ABSTRACT:
A method for spin imaging in solids using nuclear magnetic resonance (NMR) spectroscopy. The invention includes the steps of rotating the sample about an axis which makes a particular angle with the NMR static external magnetic field, rotating a magnetic field gradient with a spatial distribution which is related to the sample spinning axis synchronously with the sample, collecting the data while performing a solid state NMR line narrowing step, and changing the phase relation between the sample rotation and the field gradient rotation on a step-by-step basis to map out an image of the object.
