✦ Synopsis

Solid-state NMR imaging methods that are sensitive to slow or ultraslow molecular motion are reviewed in order to demonstrate their potential utilization for imaging of high-density macromolecular aggregates to which the low-frequency dynamics range is peculiar. The methods are based on Redfield's rotating frame saturation theory of solids, which allows information to be obtained on a time-scale given by the evolution of magnetization in an effective magnetic field of a few gauss, with the "magic" possibility of damping the static spin coupling.
