Stimulated echoes and two-dimensional nuclear magnetic resonance spectra for solids with simple line shapes.

摘要: Nuclear magnetic resonance (NMR) experiments on ion conductors often yield rather unstructured spectra, which are hard to interpret if the relation between actual translational motion of mobile species and changes NMR frequencies is not known. In order facilitate a general analysis solids with such different models for stochastic evolution considered. The treated involve random frequency jumps, diffusive evolutions, or approximately fixed jumps. Two-dimensional nuclear spectra as well stimulated-echo functions study slow ultraslow dynamics calculated Gaussian equilibrium line shapes. results compared corresponding ones from rotational experimental data.
