On. Antzutkin et al., SUPPRESSION OF SIDE-BAND IN MAGIC-ANGLE-SPINNING NUCLEAR-MAGNETIC-RESONANCE - GENERAL-PRINCIPLES AND ANALYTICAL SOLUTIONS, The Journal of chemical physics, 100(1), 1994, pp. 130-140
Several theoretical and experimental aspects of sideband suppression i
n the nuclear magnetic resonance (NMR) spectra of rotating solids are
considered. The principles of sideband suppression are explored using
general symmetry arguments and previous treatments are examined critic
ally. Analytical solutions are given for sideband suppression pulse se
quences employing four, five, six, and nine pi pulses. The analytical
solutions for four pi pulses are complete. Experimental demonstrations
are given.
