Abstract
This paper discusses manifestations of the singularities that appear in the frequency distribution when an acoustic NMR mode is excited by an rf pulse. The conditions are found for observing the power-law decay of the homogeneous precession. The macroinhomogeneousbroadening suppression effect is predicted. It is found that the nuclear spin-spin relaxation rate can be measured from the long-lived component of the induction signal.
