Introductory Remarksformulated in more detail in Sect. 47.1, a finite transverse magnetization can only appear if the spin states, i.e., primarily the wave functions, are in-phase. Such . in turn are readily generated by radio-frequency (RF) pulses exciting the whole sample in a more or less homogeneous, but neverthele

Rotary Echoesfar-reaching equivalence of experiments conducted in the laboratory and in the rotating frame has its origin in the fact that the equations of motion in both reference frames are formally identical (see Chap. 48.7). The basic phenomenon behind Hahn echoes is . about the external magnetic field. The

Surveyrtant phenomena of interest in this respect are nuclear-spin relaxation, self-diffusion, and exchange between sites with different resonance parameters. The methods in use for corresponding studies are based on very different principles. Nevertheless, one may recognize a scheme (Fig. 8.1) common to
