Using numerical optimization procedures it is shown that it is possible to design composite 180 degrees RF pulses for MAS NMR spectroscopy by explicitly taking into account the variation of the resonance offset of each crystallite during the application of the RF pulses. When using composite RF puls
A magic-angle spinning NMR method is presented which enables slow molecular motion in amorphous and partially ordered systems to be detected. In a one-dimensional experiment the spinning sidebands are modified or suppressed during a preparation period. During the following mixing period this initial
