Spin echo Fourier transform

A pulsed NMR spectrometer, with a variable frequency and variable temperature facility is best suited for the study of these disordered systems.26 27 For dipolar glasses and relaxor systems, a spin echo Fourier transformation NMR spectra of the system have been measured in a wide bore superconducting magnet ( typically at 9.2 T).

Furthermore, there have been developed special pulse methods (DEFT and SEFT, i.e. driven equilibrium Fourier transform and spin-echo Fourier transform method) for extremely slowly relaxing The cosine...
