The shapes of echo-induced EPR spectra (i.e of the field dependence of ESE signal intensity) for 15N nitroxides in organic glasses are shown to be in good agreement with those computed for the model where magnetic relaxation is caused by stochastic orientational motion of a molecule near its equilibrium position.
