Abstract:	We demonstrate here application of symmetry-adapted sequences of the form to obtain high-resolution ¹H spectra in solid-state nuclear magnetic resonance under high-speed magic-angle spinning. Experimental results are shown for samples of alanine and glycine for spinning speeds up to 30 kHz with radio-frequency nutation rates of around 100 kHz.
